Osaka
–
Osaka is a designated city in the Kansai region of Japan. Historically a merchant city, Osaka has also known as the nations kitchen. Some of the earliest signs of habitation in the Osaka area at the Morinomiya ruins comprise shell mounds, sea oysters. It is believed that what is today the Uehonmachi area consisted of a land with an inland sea in the east. During the Yayoi period, permanent habitation on the plains grew as rice farming became popular, by the Kofun period, Osaka developed into a hub port connecting the region to the western part of Japan. The large numbers of increasingly larger tomb mounds found in the plains of Osaka are seen as evidence of political-power concentration, in 645, Emperor Kōtoku built his Naniwa Nagara-Toyosaki Palace in what is now Osaka, making it the capital of Japan. The city now known as Osaka was at this time referred to as Naniwa, although the capital was moved to Asuka in 655, Naniwa remained a vital connection, by land and sea, between Yamato, Korea, and China. Naniwa was declared the capital again in 744 by order of Emperor Shōmu, and remained so until 745, in 1496, Jōdo Shinshū Buddhists established their headquarters in the heavily fortified Ishiyama Hongan-ji, located directly on the site of the old Naniwa Imperial Palace. Oda Nobunaga began a siege campaign on the temple in 1570 which ultimately resulted in the surrender of the monks. Toyotomi Hideyoshi constructed Osaka Castle in its place in 1583, Osaka was long considered Japans primary economic center, with a large percentage of the population belonging to the merchant class. Over the course of the Edo period, Osaka grew into one of Japans major cities and returned to its ancient role as a lively and its popular culture was closely related to ukiyo-e depictions of life in Edo. By 1780 Osaka had cultivated a vibrant arts culture, as typified by its famous Kabuki, in 1837 Ōshio Heihachirō, a low-ranking samurai, led a peasant insurrection in response to the citys unwillingness to support the many poor and suffering families in the area. Approximately one-quarter of the city was razed before shogunal officials put down the rebellion, Osaka was opened to foreign trade by the government of the Bakufu at the same time as Hyōgo on 1 January 1868, just before the advent of the Boshin War and the Meiji Restoration. Osaka residents were stereotyped in Edo literature from at least the 18th century, jippenisha Ikku in 1802 depicted Osakans as stingy almost beyond belief. Edo writers aspired to samurai culture, and saw themselves as poor but generous, chaste, Edo writers by contrast saw zeeroku as obsequious apprentices, stingy, greedy, gluttonous, and lewd. The modern municipality was established in 1889 by government ordinance, with an area of 15 square kilometres, overlapping todays Chūō. Later, the city went through three major expansions to reach its current size of 223 square kilometres, Osaka was the industrial center most clearly defined in the development of capitalism in Japan. It became known as the Manchester of the Orient, the rapid industrialization attracted many Korean immigrants, who set up a life apart for themselves

Ace Tone
–
Ace Electronic Industries Inc. or Ace Tone was a manufacturer of musical instruments, including electronic organs and analogue drum machines, and effects pedals. Founded in 1960 by Ikutaro Kakehashi with an investment by Sakata Shokai, Ace Tone can be considered an incarnation of the Roland Corporation. Ace Tone began manufacturing amplifiers in 1963, canary S-2 — Vacuum tube clavioline, exhibited on 1964 Summer NAMM, but not released.

Roland Corporation
–
The Roland Corporation is a Japanese manufacturer of electronic musical instruments, electronic equipment and software. It was founded by Ikutaro Kakehashi in Osaka on April 18,1972, in 2005, Rolands headquarters relocated to Hamamatsu in Shizuoka Prefecture. Today it has factories in Italy, Taiwan, Japan, as of March 31,2010, it employed 2,699 employees. It has existed in different forms since 1960, making it relatively old among still-operating manufacturers of musical electronics, known for hundreds of popular synthesizers, drum machines, and other instruments, Roland has been one of the top names in professional music equipment since the late 1970s. In 2014, Roland Corporation was subject to a management buyout by Rolands CEO Junichi Miki, Kakehashi founded Ace Electronic Industries in 1960, a manufacturer of numerous combo organs, guitar amplifiers, and effects pedals. He was also contracted by Hammond to produce machines for the companys line of home organs. In 1973, Kakehashi cut ties with companies to found Roland. As with many Japanese start-ups of the period, the name Roland was selected for export purposes as Kakehashi was interested in a name that was easy to pronounce for his worldwide target markets. Rumour has long circulated that he named his company after the French epic poem La Chanson de Roland, in reality, the name Roland was found in a telephone directory. Kakehashi opted for it as he was satisfied with the simple two-syllable word, the letter R was chosen because it was not used by many other music equipment companies, and would therefore stand out in trade show directories and industry listings. Kakehashi did not learn of The Song Of Roland until later, Roland markets products under a number of brand names, each of which are used on products geared toward a different niche. The Roland brand is used on a range of products including synthesizers, digital pianos, electronic drum systems, dance/DJ gear, guitar synthesizers, amplifiers. BOSS is a used for products geared toward guitar players and is used for guitar pedals, effects units, rhythm and accompaniment machines. Edirol was a line of professional video-editing and video-presentation systems, as well as digital audio recorders. Edirol also had Desktop Media products, more production-oriented, and included computer audio interfaces, mixers, Roland Systems Group is a line of professional commercial audio and video products. Rodgers was founded in 1958 as a company and survives today as a subsidiary of Roland, still manufacturing high-quality electric, electronic. Cakewalk music software company is a partner of Roland’s. In January 2008, Roland announced the purchase of controlling interest in the company, in 2013, ownership of Cakewalk passed from Roland to Gibson Guitar Corporation

Boss Corporation
–
Boss is a manufacturer of effects pedals for electric guitar and bass guitar. It is a division of the Roland Corporation, a Japanese manufacturer that specializes in musical equipment, in more recent times, Boss expanded their product line by including Digital Studios, rhythm machines and other electronic music equipment. The earliest Boss product was called B-100 The Boss, released in 1974 and this came with a clip-on pre-amp and a pickup to amplify acoustic guitars. At this point the Boss company had not been formed and it was technically a Beckmen Musical Instruments product. The first proper Boss foot pedal effect, the CE-1 Chorus Ensemble, was released June,1976 and it was a fairly large, AC-powered unit. Other foot pedals of that year are the GE-10, the BF-1, the Boss DS-1 was released the next year, in 1978. Their first compact chorus pedal came in 1979, and their first flanger pedal in 1980, in 1983 Boss released the DD-2 Digital Delay, the first mass-produced digital delay in a compact pedal format. The Metal Zone was released in 1991, in 1992 Boss released nine new pedals, including the Turbo Distortion. The Heavy Metal distortion pedal was a part of the guitar sound of many styles of heavy metal music ever since. The pedals all share the same footprint, for compatibility with pedal boards, Boss introduced COSM, Rolands proprietary version of digital modeling technology, into their AC-3 Acoustic Simulator pedal in 2006. Boss has since released several pedals using COSM, including the FBM-159 Fender Bassman pedal and FDR-165 Fender Deluxe Reverb pedal, all Boss compact pedals use a buffered bypass type of silent foot switching utilizing Field Effect Transistors to avoid clicks and pops. While not true bypass, the bypass has the advantage of preventing signal loss due to long runs of cable, while keeping original guitar tone intact. Boss compact pedals were originally produced in Japan, until circa 1990 when production moved to Taiwan, earlier units came with a metal screw securing the battery compartment, later models retained the metal screw, adding a plastic knob for tool-less battery removal. The labels on the bottom of the come in several different colours including black, silver, green, pink. Apart from this the design has remained unchanged for over 25 years. The DS-1 Distortion, however, is an exception, the design has changed twice throughout its lifetime. The first time was around 1994 when the Toshiba TA7136AP op-amp was replaced with the Rohm BA728N, in 2000 the op-amp was again changed. This time it was replaced with the Mitsubishi M5223AL, the latest op-amp change occurred in 2007, when new DS-1 pedals began shipping with the NJM3404AL op-amp

Electronic musical instrument
–
An electronic musical instrument is a musical instrument that produces sound using electronics. Such an instrument sounds by outputting an electrical signal that ultimately drives a loudspeaker. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, all electronic musical instruments can be viewed as a subset of audio signal processing applications. Simple electronic musical instruments are called sound effects, the border between sound effects and actual musical instruments is often hazy. Electronic musical instruments are now used in most styles of music. Development of new musical instruments, controllers, and synthesizers continues to be a highly active. In the 18th-century, musicians and composers adapted a number of instruments to exploit the novelty of electricity. The former instrument consisted of an instrument of over 700 strings. The latter was an instrument with plectra activated electrically. However, neither instrument used electricity as a sound-source, the first electric synthesizer was invented in 1876 by Elisha Gray. The Musical Telegraph used steel reeds oscillated by electromagnets and transmitted over a telephone line, Gray also built a simple loudspeaker device into later models, which consisted of a diaphragm vibrating in a magnetic field. A significant invention, which later had an effect on electronic music, was the audion in 1906. This was the first thermionic valve, or vacuum tube and which led to the generation and amplification of signals, radio broadcasting. Other early synthesizers included the Telharmonium, the Theremin, Jörg Magers Spharophon and Partiturophone, Taubmanns similar Electronde, Maurice Martenots ondes Martenot, only two models of this latter were built and the only surviving example is currently stored at the Lomonosov University in Moscow. It has been used in many Russian movies—like Solaris—to produce unusual, Hugh Le Caine, John Hanert, Raymond Scott, composer Percy Grainger, and others built a variety of automated electronic-music controllers during the late 1940s and 1950s. In 1959 Daphne Oram produced a method of synthesis, her Oramics technique, driven by drawings on a 35 mm film strip. In 1897 Thaddeus Cahill patented an instrument called the Telharmonium, using tonewheels to generate musical sounds as electrical signals by additive synthesis, it was capable of producing any combination of notes and overtones, at any dynamic level. This technology was used to design the Hammond organ

MIDI
–
A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device. These messages are sent via a MIDI cable to other devices where they control sound generation, a simple example of a MIDI setup is the use of a MIDI controller such as an electronic musical keyboard to trigger sounds created by a sound module. This MIDI data can also be recorded into a hardware or software device called a sequencer, advantages of MIDI include compactness, ease of modification and manipulation and a wide choice of electronic instruments and synthesizer or digitally-sampled sounds. MIDI technology was standardized in 1983 by a panel of industry representatives. In June 1981, Roland founder Ikutaro Kakehashi proposed the idea of standardization to Oberheim Electronics founder Tom Oberheim, in October 1981, Kakehashi, Oberheim and Smith discussed the idea with representatives from Yamaha, Korg and Kawai. Smith proposed this standard at the Audio Engineering Society show in November 1981, MIDIs development was announced to the public by Robert Moog, in the October 1982 edition of Keyboard magazine. By the time of the January 1983 Winter NAMM Show, Smith was able to demonstrate a MIDI connection between his Prophet 600 analog synthesizer and a Roland JP-6, the MIDI Specification was published in August 1983. The MIDI standard was unveiled by Ikutaro Kakehashi and Dave Smith, MIDIs appeal was originally limited to professional musicians and record producers who wanted to use electronic instruments in the production of popular music. The standard allowed different instruments to speak with other and with computers. This interoperability allowed one device to be controlled from another, which reduced the amount of hardware musicians needed to own, MIDIs introduction coincided with the dawn of the personal computer era and the introductions of samplers and digital synthesizers. The creative possibilities brought about by MIDI technology have been credited as having helped to revive the industry in the 1980s. MIDI introduced many capabilities which transformed the way musicians work, MIDI sequencing made it possible for a user with no notation skills to build complex arrangements. A musical act with as few as one or two members, each operating multiple MIDI-enabled devices, could deliver a performance which sounds similar to that of a larger group of musicians. By performing preproduction in an environment, an artist can reduce recording costs by arriving at a recording studio with a song that is already partially completed and worked out. Educational technology enabled by MIDI has transformed music education and those new to the subject of MIDI might confuse it with digital audio. MIDI symbolically represents a note, whereas digital audio represents the sound produced by the note, MIDI was invented so that musical instruments could communicate with each other and so that one instrument can control another. Analog synthesizers that have no digital component and were built prior to MIDIs development can be retrofit with kits that convert MIDI messages into analog control voltages. When a note is played on a MIDI instrument, it generates a signal that can be used to trigger a note on another instrument

Amplifier
–
An amplifier, electronic amplifier or amp is an electronic device that can increase the power of a signal. An amplifier functions by taking power from a supply and controlling the output to match the input signal shape. In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal, an amplifier is effectively the opposite of an attenuator, while an amplifier provides gain, an attenuator provides loss. An amplifier can either be a piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are used in almost all electronic equipment. Amplifiers can be categorized in different ways, another is which quantity, voltage or current is being amplified, amplifiers can be divided into voltage amplifiers, current amplifiers, transconductance amplifiers, and transresistance amplifiers. A further distinction is whether the output is a linear or nonlinear representation of the input, amplifiers can also be categorized by their physical placement in the signal chain. The first practical device that could amplify was the triode vacuum tube, invented in 1906 by Lee De Forest. Vacuum tubes were used in almost all amplifiers until the 1960s–1970s when the transistor, invented in 1947, today most amplifiers use transistors, but vacuum tubes continue to be used in some applications. Before the invention of electronic amplifiers, mechanically coupled carbon microphones were used as amplifiers in telephone repeaters. After the turn of the century it was found that negative resistance mercury lamps could amplify, the first practical electronic device that could amplify was the Audion vacuum tube, invented in 1906 by Lee De Forest, which led to the first amplifiers around 1912. The terms amplifier and amplification were first used for this new capability around 1915 when triodes became widespread, the amplifying vacuum tube revolutionized electrical technology, creating the new field of electronics, the technology of active electrical devices. It made possible long distance lines, public address systems, radio broadcasting, talking motion pictures, practical audio recording, radar, television. For 50 years virtually all electronic devices used vacuum tubes. Early tube amplifiers often had positive feedback, which could increase gain but also make the amplifier unstable, much of the mathematical theory of amplifiers was developed at Bell Telephone Laboratories during the 1920s to 1940s. Other advances in the theory of amplification were made by Harry Nyquist, the vacuum tube was the only amplifying device for 40 years, and dominated electronics until 1947, when the first transistor, the BJT, was invented. Today most amplifiers use transistors, but vacuum tubes are used in some high power applications such as radio transmitters. All amplifiers have gain, a factor that relates the magnitude of some property of the output signal to a property of the input signal

Effects unit
–
An effects unit or pedal is an electronic or digital device that alters how a musical instrument or other audio source sounds. In the 2010s, most effects use solid state electronics and/or computer chips, some vintage effects units from the 1930s to the 1970s and modern reissues of these effects use mechanical components as well or vacuum tubes. Musicians, audio engineers and record producers use effects units during live performances or in the studio, typically with electric guitar, electronic keyboard, while guitar effects are most frequently used with electric or electronic instruments, effects can also be used with acoustic instruments, drums and vocals. Rackmounted or audio console-integrated reverb effects are used with vocals in live sound and sound recording. Examples of common units include wah-wah pedals, fuzzboxes and reverb units. A stompbox or pedal is a metal or plastic box placed on the floor in front of the musician and connected to the instrument. Pedals are usually the least expensive format, a rackmount device mounts on a standard 19-inch equipment rack and usually contains several types of effects. Rackmount effects typically have buttons and/or knobs on the face of the chassis for controlling the effects, an effects unit is also called an effect box, effects device, effects processor or simply effects. In audio engineer parlance, a signal without effects is dry, the abbreviation F/X or FX is sometimes used. A pedal-style unit may be called a box, stompbox. When a musician has multiple effects in a rack mounted road case, Effects units are available in a variety of formats or form factors. Stompboxes are usually the smallest, least expensive, and most rugged effects units, rackmount devices are generally more expensive and offer a wider range of functions. An effects unit can consist of analog or digital circuitry or a combination of the two, during a live performance, the effect is plugged into the electrical signal path of the instrument. In the studio, the instrument or other sound-sources auxiliary output is patched into the effect, form factors are part of a studio or musicians outboard gear. Stompboxes are small plastic or metal chassis which usually lie on the floor or in a pedalboard to be operated by the users feet, pedals are often rectangle-shaped, but there are a range of other shapes. Typical simple stompboxes have a single footswitch, one to three potentiometers for controlling the effect, and a single LED that indicates if the effect is on, depending on the type of pedal, the potentiometers may control different parameters of the effect. For a chorus effect, for example, the knobs may control the depth, some pedals have two knobs stacked on top of each other, enabling the unit to provide two knobs per single knob space. An effects chain or signal chain is formed by connecting two or more stompboxes, effect chains are typically created between the guitar and the amp or between the preamplifier and the power amp

Roland TR-808
–
The Roland TR-808 Rhythm Composer, often referred to simply as the 808, is a drum machine introduced by the Roland Corporation in 1980 and discontinued in 1983. It was one of the earliest programmable drum machines, with which users could create their own rather than having to use presets. Unlike its nearest competitor, the expensive and sample-based Linn LM-1 Drum Computer. Launched at a time when music had yet to become mainstream. It was succeeded in 1984 by the TR-909, over the course of the decade, the 808 attracted a cult following among underground musicians for its affordability, ease of use, and idiosyncratic sounds, particularly its deep, booming bass drum. It became a cornerstone of the electronic, dance, and hip hop genres, popularized by early hits such as Marvin Gayes Sexual Healing and Afrika Bambaataa. At the time, drum machines were most often used to accompany home organs, Lewis was known for performances using electronic instruments he had modified himself, decades before the popularization of instrument hacking via circuit bending. He made extensive modifications to the Ace Tone drum machine, creating his own rhythms and wiring the device through his organs expression pedal to accent the percussion, unique at the time. Lewis was approached by Ace Tone president and founder Ikutaro Kakehashi, in 1972, Kakehashi formed the Roland Corporation and hired Lewis to help design drum machines. By the late 1970s, microprocessors were appearing in such as the Sequential Circuits Prophet-5 synthesizer. In 1978, Roland released the CompuRhythm CR-78, the first drum machine with which users could write, save, with its next machine, the TR-808, Roland aimed to develop a drum machine for the professional market, expecting that it would mainly be used to create demos. Though the engineers aimed to emulate real percussion, the prohibitive cost of memory drove them to design sound-generating hardware instead of using samples, Kakehashi deliberately purchased faulty transistors to create the machines distinctive sizzling sound. Roland engineer Makoto Muri credited the design of the voice circuits to Mr. Nakamura. The 808 generates 16 different sounds in imitation of acoustic percussion, bass drum, snare, toms, conga, rimshot, claves, handclap, maraca, cowbell, cymbal, and hi-hat. It is completely analog, meaning its sounds are generated via hardware rather than sampled, users can program up to 32 patterns using the step sequencer, each with a maximum of 768 measures, and place accents on individual beats, a feature introduced with the CR-78. Users can also set the tempo and time signature, including unusual signatures such as 5/4, the machine has multiple audio outputs and a DIN sync port to synchronize with other devices, considered groundbreaking at the time. The 808s sounds do not resemble real percussion, and have described as clicky and hypnotic, robotic, toy-like, spacey. Fact described them as a combination of tones and white noise

Roland TR-909
–
The Roland TR-909 Rhythm Composer is a partially analog, partially sample-based, drum machine introduced by the Japanese Roland Corporation in 1984. The brainchild of Tadao Kikumoto, the engineer behind the Roland TB-303, it features a 16-step step sequencer and it is fully programmable, and like its predecessor, the TR-808, it can store entire songs with multiple sections, as opposed to simply storing patterns. It was the first MIDI-equipped drum machine, the 909 was launched three years after its 808 forebear, changing the game slightly by offering a part-analogue, part-sample-based sound generation hybrid. As with the 808, the 909 sounded a long way from the more realistic alternatives from Linn and Oberheim that had all, more expensive, sample-based drum computers were better at faithfully reproducing real drum sounds, while the TR-909 sounded synthetic. One of the first Roland instruments to be equipped with MIDI, but, like the TR808 before it, nobody could have predicted the reverence in which the TR909 would eventually come to be held. The TR909 soundset is part of Rolands AIRA TR-8 drum machine, on September 9,2016, 30+ years after the TR909 was introduced, Roland declared the day 909 Day. The event is being celebrated by the unveiling of over 30 new instruments, unlike its purely analog ancestor, the TR-09 is powered by the same analog modeling technology that powers the AIRA TR-8. The TR-09 is part of Rolands Boutique product line, the hi-hats and cymbals are 6-bit samples, compressed and combined with a volume envelope curve to allow slight modification. Thanks to the circuitry, various aspects of the drum sound can be modified. There is also a feature called accent—a primitive means of humanizing the drumbeat, in a simplified model of a drummer and a kit, the loudness of the sound created would basically depend on the velocity at which the drummer hits a given part of the kit. A human drummer can emphasize certain notes by playing louder. Part of the charm of the TR-909 comes from its 16-step sequencer — the 16 buttons along the bottom of the interface correspond to the 16th notes of a bar in 4/4 meter. For example, punching the buttons 1,5,9 and 13 on the drum part would create a simple four to the floor beat. While the sequencer is running, a light runs from step 1 to step 16, the TR-909 has several editing modes, pattern editing where one focuses solely on the 16 steps, and track editing, which allows for chaining various patterns in a row. Because it has MIDI, its possible to control other instruments with the sequencer.

Roland TB-303
–
The TB-303 played an important role in the development of house music, influencing Chicago house and forming the basis for acid house. It is also used in related dance genres such as acid techno. The TB-303 was originally marketed to guitarists for bass accompaniment while practicing alone, production lasted approximately 18 months, resulting in only 10,000 units. It was not until the mid- to late-1980s that DJs and electronic musicians in Chicago found a use for the machine in the context of the newly developing house music genre. The TB-303 has an audio oscillator, which may be configured to produce either a sawtooth wave or a square wave. The square wave is derived from the sawtooth waveform using a simple and this produces a sound that is subtly different from the square waveform created by the dedicated hardware found in most analog synthesizers. It also includes an envelope generator, with a decay control only. A lowpass filter is included, with -24dB per octave attenuation, and controls for cutoff frequency, resonance. It is a misconception that the filter is a 3 pole 18 dB per octave design when in fact it is 4-pole 24 dB per octave. The TB-303 sequencer has some features that contribute to its characteristic sound. During the programming of a sequence, the user can determine whether a note should be accented, and whether it should employ portamento, a smooth transition to the following note. The portamento circuitry employs a fixed time, meaning that whatever the interval between notes, the time taken to reach the correct pitch is always the same. The accent circuitry, as well as increasing the amplitude of a note, also emphasizes the EG filters cutoff and resonance, resulting in a distinctive, the instrument also features a simple step-time method for entering note data into the 16-step programmable sequencer. This was notoriously difficult to use, and would result in entering a different sequence than the one that had been intended. Some users also take advantage of a low voltage failure mode, rip It Up by Scottish post-punk band Orange Juice, which reached #8 in the UK singles chart in February 1983, was the first UK hit to feature the synthesiser. In the late 1980s and early 1990s, as new Acid styles emerged, examples of this technique include Phutures 1987 Acid Tracks, Hardfloors 1992 EP Acperience and Interlect 3000s 1993 EP Volcano. Jesse Saunders also utilized the TB-303 with a Roland TR-808 drum machine, in other instances the TB-303 was extremely distorted and processed, such as Josh Winks 1995 hit Higher State of Consciousness. The acid sound is produced by playing a repeating note pattern on the TB-303, while altering the filters cutoff frequency, resonance

Synthesizer
–
A synthesizer is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals, natural sounds like ocean waves, etc. or generate new electronic timbres. Synthesizers without built-in controllers are called sound modules, and are controlled via USB, MIDI or CV/gate using a controller device. Synthesizers use various methods to generate electronic signals, synthesizers were first used in pop music in the 1960s. In the 1970s, synths were used in disco, especially in the late 1970s, in the 1980s, the invention of the relatively inexpensive, mass market Yamaha DX7 synth made synthesizers widely available. 1980s pop and dance music often made use of synthesizers. In the 2010s, synthesizers are used in genres of pop, rock. Contemporary classical music composers from the 20th and 21st century write compositions for synthesizer, the beginnings of the synthesizer are difficult to trace, as it is difficult to draw a distinction between synthesizers and some early electric or electronic musical instruments. One of the earliest electric musical instruments, the telegraph, was invented in 1876 by American electrical engineer Elisha Gray. He accidentally discovered the sound generation from a self-vibrating electromechanical circuit and this musical telegraph used steel reeds with oscillations created by electromagnets transmitted over a telegraph line. Gray also built a simple loudspeaker device into later models, consisting of a diaphragm in a magnetic field. This instrument was a remote electromechanical musical instrument that used telegraphy, though it lacked an arbitrary sound-synthesis function, some have erroneously called it the first synthesizer. In 1897, Thaddeus Cahill invented the Teleharmonium, which used dynamos, and was capable of additive synthesis like the Hammond organ, however, Cahills business was unsuccessful for various reasons, and similar but more compact instruments were subsequently developed, such as electronic and tonewheel organs. In 1906, American engineer, Lee De Forest ushered in the electronics age and he invented the first amplifying vacuum tube, called the Audion tube. This led to new entertainment technologies, including radio and sound films, ondes Martenot and Trautonium were continuously developed for several decades, finally developing qualities similar to later synthesizers. In the 1920s, Arseny Avraamov developed various systems of graphic sonic art, in 1938, USSR engineer Yevgeny Murzin designed a compositional tool called ANS, one of the earliest real-time additive synthesizers using optoelectronics. The earliest polyphonic synthesizers were developed in Germany and the United States, during the three years that Hammond manufactured this model,1,069 units were shipped, but production was discontinued at the start of World War II. Both instruments were the forerunners of the electronic organs and polyphonic synthesizers

Roland MC-8 Microcomposer
–
The Roland MC-8 MicroComposer by the Roland Corporation was introduced in early 1977 at a list price of US$4,795. It was one of the earliest stand-alone microprocessor-driven CV/Gate music sequencers, following EMS Sequencer 256 in 1971 and it also allowed the user to allocate multiple pitch CVs to a single Gate channel, creating polyphonic parts within the overall sequence. Due to the price, only 200 units were sold worldwide. The MC-8 was designed to work with large complex modular synthesizers such as the System 700 and it could also be used during a live performance to control lighting by using pre-programmed, timed pulses, and pre-programmed timed voltage levels. The MC-8 was based on a developed by Canadian Ralph Dyck. Backup was via cassette and could take 45 minutes to an hour for a three- or four-minute piece of music to back up, the memory was volatile, so a loss of power meant complete loss of data. All parameters were variable so the scale and time-base could be assigned values to suit the needs of the piece being programmed. This made the extremely versatile but somewhat unfriendly to approach for the first time. While only 200 units were sold worldwide, the MC-8 was a revolutionary product, the MC-8 provided eight control voltage outputs and eight gate outputs, as well as a six-bit multiplex output with a special seventh bit set aside for portamento control. At the time, Billboard noted that the use of such computer-based technology in conjunction with synthesizers allowed Yellow Magic Orchestra to create new sounds that were not possible until then. The band later described the MC-8, along with member Hideki Matsutake who programmed it, richard James Burgess and John L. Walters from the band Landscape were also among the first major commercial users of the MC-8. They triggered various synths such as the Roland System 100 and Moogs which also used CV/Gate, Burgess created the drum parts by using the multiplex outputs of the MC8 to trigger the prototype, breadboard version of the SDS5 drum synthesizer. Most of the album From the Tea-rooms of Mars was made this way, Burgess and Walters demonstrated the MC-8 on BBC TVs Tomorrows World.

Music sequencer
–
This software also improved on the quality of the earlier sequencers which tended to be mechanical sounding and were only able to play back notes of exactly equal duration. Software-based sequencers allowed musicians to program performances that were more expressive and these new sequencers could also be used to control external synthesizers, especially rackmounted sound modules, and it was no longer necessary for each synthesizer to have its own devoted keyboard. As the technology matured, sequencers gained more features, such as the ability to record multitrack audio, Sequencers used for audio recording are called digital audio workstations. Many modern sequencers can be used to control virtual instruments implemented as software plug-ins and this allows musicians to replace expensive and cumbersome standalone synthesizers with their software equivalents. Today the term sequencer is used to describe software. Workstation keyboards have their own proprietary built-in MIDI sequencers, drum machines and some older synthesizers have their own step sequencer built in. There are still also standalone hardware MIDI sequencers, although the demand for those has diminished greatly due to the greater feature set of their software counterparts. Music sequencers are often categorized by handling data types, as following, or, the phrase samplers including Groove machines, etc. Also, music sequencer can be categorized by its construction and supporting modes, realtime sequencers record the musical notes in real-time as on audio recorders, and play back musical notes with designated tempo, quantizations, and pitch. For editing, usually punch in/punch out feature originated in the recording is provided. For detailed editing, possibly another visual editing modes under graphical user interface may be more suitable, anyway, this mode provides usability similar to the audio recorder already familiarized by musicians, and it is widely supported on software sequencer, DAW, and built-in hardware sequencers. Analog sequencers are typically implemented with analog electronics, and play the musical notes designated by a series of knobs or sliders corresponding to each musical note and it is designed for both composition and live performance, users can change the musical notes at any time without regarding recording mode. And also possibly, the time-interval between each note can be independently adjustable. Typically, analog sequencer is used to generate the repeated minimalistic phrases which is reminiscent of Tangerine Dream, on the bass machines, select a step note from a chromatic keypads, then select a step duration from a group of length-buttons, sequentially. In general, step mode, along with roughly quantized semi-realtime mode, is supported on the analog drum machines, bass machines. Software sequencer is a class of application software providing a functionality of music sequencer, the features provided as sequencers vary widely depending on the software, even an analog sequencer can be simulated. The user may control the software sequencer either by using the user interfaces or a specialized input devices. The early music sequencers were sound producing devices such as musical instruments, music boxes, mechanical organs, player pianos

Guitar amplifier
–
The input of modern guitar amplifiers is a 1/4 jack, which is fed a signal from an electro-magnetic pickup or a piezoelectric pickup using a patch cord, or a wireless transmitter. For electric guitar players, their choice of guitar amp and the settings they use on the amplifier are a key part of their signature tone or sound, some guitar players are longtime users of a specific amp brand or model. Many electric guitar players use external effects pedals to alter the sound of their tone before the signal reaches the guitar amp, such as the wah wah pedal and this article focuses on electric guitar amps. For information on amps for guitar, a lower-pitched, similar instrument. More expensive amplifiers typically have controls for other frequency ranges. Some guitar amplifiers have a graphic equalizer, which uses vertical fader controls which can control many frequency bands, the first amplifier stage is a preamplifier stage, which amplifies the guitar signal to a level that can drive the power stage. The power amplifier or output stage produces a current signal to drive a loudspeaker to produce sound that the guitarist. Amplifiers may use vacuum tubes, solid-state devices, or both, a wide range of speaker configurations are available in guitar cabinets, ranging from cabinets with a single speaker or multiple speakers. Guitar amplifiers have a range in price and quality. Music equipment companies import small, low-powered practice amplifiers for students, other companies produce expensive custom-made amplifiers for professional musicians, which can cost thousands of dollars. Most combo amplifiers have a handle, and many combo amplifiers. Control knobs are typically mounted on the front of the cabinet or chassis, though in some cases, the most basic amps only have a few knobs, which typically control volume, bass and treble. More expensive amps may have a number of knobs that control pre-amp volume, distortion or overdrive, volume, bass, mid and treble, some older amps have a knob that controls a vibrato effect. The 1/4 input jack is typically mounted on the front of the amplifier, in the simplest, least expensive amplifiers, this 1/4 jack is the only jack on the amplifier. Some amps have a 1/4 jack for connecting a pedal to turn the amps onboard overdrive and reverb on, the cone speaker, widely used in 2000s-era amp cabinets, was not offered for sale until 1925. The first amplifiers and speakers could only be powered with large batteries, when engineers developed the first AC mains-powered amplifiers, they were soon used to make musical instruments louder. Engineers invented the first loud, powerful amplifier and speaker systems for public address systems and these large PA systems and movie theatre sound systems were very large and very expensive, and so they could not be used by most touring musicians. During the late 1920s to mid-1930s, small portable PA systems, in 1928, the Stromberg-Voisinet firm was the first company to sell an electric stringed instrument and amplifier package

Popular music
–
Popular music is music with wide appeal that is typically distributed to large audiences through the music industry. These forms and styles can be enjoyed and performed by people with little or no musical training and it stands in contrast to both art music and traditional or folk music. Art music was historically disseminated through the performances of music, although since the beginning of the recording industry. Traditional music forms such as blues songs or hymns were passed along orally, or to smaller. The original application of the term is to music of the 1880s Tin Pan Alley period in the United States, although popular music sometimes is known as pop music, the two terms are not interchangeable. Popular music songs and pieces typically have easily singable melodies, in the 2000s, with songs and pieces available as digital sound files, it has become easier for music to spread from one country or region to another. Some popular music forms have become global, while others have an appeal within the culture of their origin. Through the mixture of genres, new popular music forms are created to reflect the ideals of a global culture. The examples of Africa, Indonesia and the Middle East show how Western pop music styles can blend with local traditions to create new hybrid styles. Sales of recordings or sheet music are one measure, middleton and Manuel note that this definition has problems because multiple listens or plays of the same song or piece are not counted. Manuel states that one criticism of music is that it is produced by large media conglomerates and passively consumed by the public. He claims that the listeners in the scenario would not have been able to make the choice of their favorite music, moreover, understandings of popular music have changed with time. A societys popular music reflects the ideals that are prevalent at the time it is performed or published, david Riesman states that the youth audiences of popular music fit into either a majority group or a subculture. The majority group listens to the commercially produced styles while the subcultures find a minority style to transmit their own values and this allows youth to choose what music they identify with, which gives them power as consumers to control the market of popular music. Form in popular music is most often sectional, the most common sections being verse, chorus or refrain, other common forms include thirty-two-bar form, chorus form *, and twelve-bar blues. Popular music songs are rarely composed using different music for each stanza of the lyrics, the verse and chorus are considered the primary elements. Each verse usually has the melody, but the lyrics change for most verses. The chorus usually has a phrase and a key lyrical line which is repeated

Electronic music
–
In general, a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer. During the 1920s and 1930s, electronic instruments were introduced and the first compositions for instruments were composed. Musique concrète, created in Paris in 1948, was based on editing together recorded fragments of natural and industrial sounds, Music produced solely from electronic generators was first produced in Germany in 1953. Electronic music was created in Japan and the United States beginning in the 1950s. An important new development was the advent of computers for the purpose of composing music, algorithmic composition was first demonstrated in Australia in 1951. In America and Europe, live electronics were pioneered in the early 1960s, during the 1970s to early 1980s, the monophonic Minimoog became once the most widely used synthesizer at that time in both popular and electronic art music. In the 1980s, electronic music became dominant in popular music, with a greater reliance on synthesizers, and the adoption of programmable drum machines. Electronically produced music became prevalent in the domain by the 1990s. Contemporary electronic music includes many varieties and ranges from art music to popular forms such as electronic dance music. Today, pop music is most recognizable in its 4/4 form. At the turn of the 20th century, experimentation with emerging electronics led to the first electronic musical instruments and these initial inventions were not sold, but were instead used in demonstrations and public performances. The audiences were presented with reproductions of existing music instead of new compositions for the instruments, while some were considered novelties and produced simple tones, the Telharmonium accurately synthesized the sound of orchestral instruments. It achieved viable public interest and made progress into streaming music through telephone networks. Critics of musical conventions at the time saw promise in these developments, ferruccio Busoni encouraged the composition of microtonal music allowed for by electronic instruments. He predicted the use of machines in future music, writing the influential Sketch of a New Esthetic of Music, futurists such as Francesco Balilla Pratella and Luigi Russolo began composing music with acoustic noise to evoke the sound of machinery. They predicted expansions in timbre allowed for by electronics in the influential manifesto The Art of Noises, developments of the vacuum tube led to electronic instruments that were smaller, amplified, and more practical for performance. In particular, the theremin, ondes Martenot and trautonium were commercially produced by the early 1930s, from the late 1920s, the increased practicality of electronic instruments influenced composers such as Joseph Schillinger to adopt them

Hip hop music
–
It developed as part of hip hop culture, a subculture defined by four key stylistic elements, MCing/rapping, DJing/scratching with turntables, break dancing, and graffiti writing. Other elements include sampling beats or bass lines from records, while often used to refer solely to rapping, hip hop more properly denotes the practice of the entire subculture. Hip hops early evolution occurred as sampling technology and drum machines became available and affordable. Turntablist techniques such as scratching and beatmatching developed along with the breaks and Jamaican toasting, rapping developed as a vocal style in which the artist speaks or chants along rhythmically with an instrumental or synthesized beat. The Sugarhill Gangs 1979 song Rappers Delight is widely regarded to be the first hip hop record to gain popularity in the mainstream. The 1980s marked the diversification of hip hop as the genre developed more complex styles, prior to the 1980s, hip hop music was largely confined within the United States. However, during the 1980s, it began to spread to scenes in dozens of countries. New school hip hop was the wave of hip hop music, originating in 1983–84 with the early records of Run-D. M. C. The Golden age hip hop period was a period between the mid-1980s and the early 1990s. Notable artists from this era include the Juice Crew, Public Enemy, & Rakim, Boogie Down Productions and KRS-One, EPMD, Slick Rick, Beastie Boys, Kool G Rap, Big Daddy Kane, Ultramagnetic MCs, De La Soul, and A Tribe Called Quest. Gangsta rap is a subgenre of hip hop that often focuses on the violent lifestyles, in the West Coast hip hop style, G-funk dominated mainstream hip hop for several years during the 1990s. I. G. In the 1990s, hip hop began to diversify with other regional styles emerging, such as Southern rap, at the same time, hip hop continued to be assimilated into other genres of popular music, examples being Neo soul and nu metal. Hip hop became a pop music genre in the mid-1990s. The popularity of hip hop music continued through the 2000s, with hip hop influences also increasingly finding their way into mainstream pop, the United States also saw the success of regional styles such as crunk, a Southern genre that emphasized the beats and music more than the lyrics. Starting in 2005, sales of hip hop music in the United States began to severely wane, during the mid-2000s, alternative hip hop secured a place in the mainstream, due in part to the crossover success of artists such as OutKast and Kanye West. Creation of the hip hop is often credited to Keith Cowboy, rapper with Grandmaster Flash. However, Lovebug Starski, Keith Cowboy, and DJ Hollywood used the term when the music was known as disco rap. Cowboy later worked the hip hop cadence into a part of his stage performance, the first use of the term in print was in The Village Voice, by Steven Hager, later author of a 1984 history of hip hop

Contemporary R&B
–
Contemporary R&B, also known as simply R&B, is a music genre that combines elements of rhythm and blues, soul, funk, pop, hip hop and dance. The genre features a record production style, drum machine-backed rhythms, an occasional saxophone-laced beat to give a jazz feel. Electronic influences are becoming a trend and the use of hip hop or dance-inspired beats are typical, although the roughness. Contemporary R&B vocalists are often known for their use of melisma, popularized by such as Michael Jackson, R. Kelly, Craig David, Stevie Wonder, Whitney Houston. That same year, Teddy Riley began producing R&B recordings that included hip hop influences and this combination of R&B style and hip hop rhythms was termed new jack swing and was applied to artists such as Bobby Brown, Keith Sweat, Al B. Guy, Jodeci and Bell Biv DeVoe, the style became less popular by the end of the 1990s, but later experienced a resurgence. In 1990 Mariah Carey released Vision of Love as her debut single and it was immensely popular peaking at number 1 in many worldwide charts including the Billboard Hot 100, and it propelled Mariahs carrier. The song is said to have popularized the use of melisma. During the mid-1990s, Whitney Houstons The Bodyguard, Original Soundtrack Album sold over 40 million copies becoming the best-selling soundtrack of all time. Janet Jacksons self-titled fifth studio album janet. which came after her historic multimillion-dollar contract with Virgin Records, sold over twenty million copies worldwide. Boyz II Men and Mariah Carey recorded several Billboard Hot 100 No.1 hits, including One Sweet Day, Carey also released a remix of her 1995 single Fantasy, with Ol Dirty Bastard as a feature, a collaboration format that was unheard of at this point. Carey, Boyz II Men and TLC released albums in 1994 and 1995—Daydream, II and CrazySexyCool. In the late 1990s, neo soul, which added 1970s soul influences to the hip hop soul blend, arose, led by such as DAngelo, Erykah Badu. Hill and Missy Elliott further blurred the line between R&B and hip hop by recording both styles, beginning in 1995, the Grammy Awards enacted the Grammy Award for Best R&B Album, with II by Boyz II Men becoming the first recipient. The award was received by TLC for CrazySexyCool in 1996, Tony Rich for Words in 1997, Erykah Badu for Baduizm in 1998. At the end of 1999, Billboard magazine ranked Mariah Carey and Janet Jackson as the first, simultaneously, in the second half of the 1990s, The Neptunes and Timbaland set influential precedence on contemporary R&B and hip hop music. R&B acts such as Michael Jackson, Whitney Houston, Janet Jackson, Mariah Carey, Usher, in 2001, Alicia Keys released Fallin as her debut single. It peaking at one on the Billboard Hot 100, Mainstream Top 40

Rock music
–
It has its roots in 1940s and 1950s rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of genres such as electric blues and folk. Musically, rock has centered on the guitar, usually as part of a rock group with electric bass guitar. Typically, rock is song-based music usually with a 4/4 time signature using a verse-chorus form, like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. Punk was an influence into the 1980s on the subsequent development of subgenres, including new wave, post-punk. From the 1990s alternative rock began to rock music and break through into the mainstream in the form of grunge, Britpop. Similarly, 1970s punk culture spawned the visually distinctive goth and emo subcultures and this trio of instruments has often been complemented by the inclusion of other instruments, particularly keyboards such as the piano, Hammond organ and synthesizers. The basic rock instrumentation was adapted from the blues band instrumentation. A group of musicians performing rock music is termed a rock band or rock group, Rock music is traditionally built on a foundation of simple unsyncopated rhythms in a 4/4 meter, with a repetitive snare drum back beat on beats two and four. Melodies are often derived from older musical modes, including the Dorian and Mixolydian, harmonies range from the common triad to parallel fourths and fifths and dissonant harmonic progressions. Critics have stressed the eclecticism and stylistic diversity of rock, because of its complex history and tendency to borrow from other musical and cultural forms, it has been argued that it is impossible to bind rock music to a rigidly delineated musical definition. These themes were inherited from a variety of sources, including the Tin Pan Alley pop tradition, folk music and rhythm, as a result, it has been seen as articulating the concerns of this group in both style and lyrics. Christgau, writing in 1972, said in spite of some exceptions, rock and roll usually implies an identification of male sexuality, according to Simon Frith rock was something more than pop, something more than rock and roll. Rock musicians combined an emphasis on skill and technique with the concept of art as artistic expression, original. The foundations of music are in rock and roll, which originated in the United States during the late 1940s and early 1950s. Its immediate origins lay in a melding of various musical genres of the time, including rhythm and blues and gospel music, with country. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, debate surrounds which record should be considered the first rock and roll record. Other artists with rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis

Pop music
–
Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid 1950s. The terms popular music and pop music are used interchangeably, although the former describes all music that is popular. Pop and rock were synonymous terms until the late 1960s, when they were used in opposition from each other. Although pop music is seen as just the singles charts, it is not the sum of all chart music. Pop music is eclectic, and often borrows elements from other such as urban, dance, rock, Latin. Identifying factors include generally short to medium-length songs written in a format, as well as the common use of repeated choruses, melodic tunes. David Hatch and Stephen Millward define pop music as a body of music which is distinguishable from popular, jazz, according to Pete Seeger, pop music is professional music which draws upon both folk music and fine arts music. Although pop music is seen as just the singles charts, it is not the sum of all chart music, the music charts contain songs from a variety of sources, including classical, jazz, rock, and novelty songs. Pop music, as a genre, is seen as existing and developing separately, pop music continuously evolves along with the terms definition. The term pop song was first recorded as being used in 1926, Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country, blues and hillbilly music. The Oxford Dictionary of Music states that while pops earlier meaning meant concerts appealing to a wide audience. Since the late 1950s, however, pop has had the meaning of non-classical mus, usually in the form of songs, performed by such artists as the Beatles. Grove Music Online also states that, in the early 1960s pop music competed terminologically with beat music, while in the USA its coverage overlapped with that of rock and roll. From about 1967, the term was used in opposition to the term rock music. Whereas rock aspired to authenticity and an expansion of the possibilities of music, pop was more commercial, ephemeral. It is not driven by any significant ambition except profit and commercial reward, and, in musical terms, it is essentially conservative. It is, provided from on high rather than being made from below, pop is not a do-it-yourself music but is professionally produced and packaged. The beat and the melodies tend to be simple, with limited harmonic accompaniment, the lyrics of modern pop songs typically focus on simple themes – often love and romantic relationships – although there are notable exceptions

Electric organ
–
An electronic organ is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally, it was designed to imitate the sound of pipe organs, theatre organs, band sounds, or orchestral sounds. In a fashion not totally unlike that of organs, reed organs generated sound by forcing air over a set of reeds by means of a bellows. While reed organs had limited tonal quality, they were small, inexpensive, self-powered, the reed organ was thus able to bring an organlike sound to venues that were incapable of housing or affording pipe organs. This concept was to play an important role in the development of the electric organ, pipe organ In the 1930s, several manufacturers developed electronic organs designed to imitate the function and sound of pipe organs. At the time, some thought that emulation of the pipe organ was the most promising route to take in the development of an electronic organ. Various types of organs have been brought to market over the years. Electricity arrived on the scene in the first decades of the 20th century. Electrically powered reed organs appeared during the first decades of electricity, cahills techniques were later used by Laurens Hammond in his organ design, and the 200-ton Telharmonium served as the worlds first demonstration of electrically produced music on a grand scale. Meanwhile, some experimentation with producing sound by electric impulses was taking place. Built in Belleville, Ontario, the Robb Wave Organ predates its much more successful competitor Hammond by patent and manufacture, the first widespread success in this field was a product of the Hammond Corporation in 1934. The Hammond organ quickly became the successor of the reed organ, from the start, electronic organs operated on a radically different principle from all previous organs. The organ was electrically powered, replacing the reed organs twin bellows pedals with a swell pedal more like that of a pipe organ. Instead of having to pump at a constant rate, as had been the case with the reed organ, from the beginning, the electronic organ had a second manual, also rare among reed organs. The most revolutionary difference in the Hammond, however, was its number of tonewheel settings. By using the drawbars, the organist could combine a variety of tones and harmonics in varying proportions. In all, the Hammond was capable of producing more than 250 million tones, the classic Hammond sound benefitted from the use of free-standing loudspeakers called tone cabinets that produced a higher-quality sound than small built-in speakers. The sound was further enhanced by rotating speaker units, usually manufactured by Leslie

Hammond organ
–
The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Various models have been produced, most of use sliding drawbars to create a variety of sounds. Around two million Hammond organs have been manufactured, the organ is commonly used with, and associated with, the Leslie speaker. The organ was originally marketed and sold by the Hammond Organ Company to churches as a lower-cost alternative to the pipe organ. It quickly became popular with jazz musicians in organ trios. Organ trios were hired by jazz club owners, who found that organ trios were a cheaper alternative to hiring a big band. The Hammond Organ Company struggled financially during the 1970s as they abandoned tonewheel organs and these instruments were not as popular with musicians as the tonewheels had been, and the company went out of business in 1985. The Hammond name was purchased by the Suzuki Musical Instrument Corporation and this culminated in the production of the New B-3 in 2002, which provided an accurate recreation of the original B-3 organ using modern digital technology. Hammond-Suzuki continues to manufacture a variety of organs for both players and churches. Other companies, such as Korg, Roland and Clavia, have achieved success in providing emulations of the original tonewheel organs. The sound of a tonewheel Hammond can also be emulated using software such as Native Instruments B4. A number of distinctive Hammond organ features are not usually found on other keyboards like the piano or synthesizer, Some are similar to a pipe organ, but others are unique to the instrument. Most Hammond organs have two 61-note keyboards called manuals, as with pipe organ keyboards, the two manuals are arrayed on two levels close to each other. There is no difference in volume regardless of how heavily or lightly the key is pressed, the keys on each manual have a lightweight action, which allows players to perform rapid passages more easily than on a piano. In contrast to piano and pipe organ keys, Hammond keys have a flat-front profile, Early Hammond console models had sharp edges, but starting with the B-2 these were rounded, as they were cheaper to manufacture. The M series of spinets also had waterfall keys, but later models had diving board style keys which resembled those found on a church organ. Modern Hammond-Suzuki models use waterfall keys, Hammond console organs come with a wooden pedalboard played with the feet, for bass notes. Most console Hammond pedalboards have 25 notes, with the note a low C

Music industry
–
The modern Western music industry emerged between the 1930s and 1950s, when records replaced sheet music as the most important product in the music business. In the commercial world, the recording industry–a reference to recording performances of songs and pieces, labels outside of these three major labels are referred to as independent labels. The largest portion of the music market for concerts and tours is controlled by Live Nation. Live Nation is a subsidiary of iHeartMedia Inc, which is the largest owner of radio stations in the United States. In the first decades of the 2000s, the industry underwent drastic changes with the advent of widespread digital distribution of music via the Internet. A conspicuous indicator of changes is total music sales, since 2000. In 2011, the largest recorded music retailer in the world was now a digital, Internet-based platform operated by a computer company, printed music in Europe, Music publishing using machine-printed sheet music developed during the Renaissance music era in the mid-15th century. The development of music followed the evolution of printing technologies that were first developed for printing regular books. After the mid-15th century, mechanical techniques for printing music were first developed. The earliest example, a set of chants, dates from about 1465. Prior to this time, music had to be copied out by hand, to copy music notation by hand was a very costly, labor-intensive and time-consuming process, so it was usually undertaken only by monks and priests seeking to preserve sacred music for the church. The few collections of music that are extant were commissioned and owned by wealthy aristocrats. Examples include the Squarcialupi Codex of Italian Trecento music and the Chantilly Codex of French Ars subtilior music, the use of printing enabled sheet music to reproduced much more quickly and at a much lower cost than hand-copying music notation. This helped musical styles to spread to cities and countries more quickly. With music printing, though, a composers music could be printed, as sheet music of major composers pieces and songs began to be printed and distributed in a wider area, this enabled composers and listeners to hear new styles and forms of music. A German composer could buy songs written by an Italian or English composer, and this led to more blending of musical styles from different countries and regions. The pioneer of music printing was Ottaviano Petrucci, a printer and publisher who was able to secure a twenty-year monopoly on printed music in Venice during the 16th century. Venice was one of the business and music centers during this period

Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an occupation in the later half of the 19th century after commercialization of the electric telegraph, the telephone. Subsequently, broadcasting and recording media made electronics part of daily life, the invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object. Electrical engineers typically hold a degree in engineering or electronic engineering. Practicing engineers may have professional certification and be members of a professional body, such bodies include the Institute of Electrical and Electronics Engineers and the Institution of Engineering and Technology. Electrical engineers work in a wide range of industries and the skills required are likewise variable. These range from basic circuit theory to the management skills required of a project manager, the tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software. Electricity has been a subject of scientific interest since at least the early 17th century and he also designed the versorium, a device that detected the presence of statically charged objects. In the 19th century, research into the subject started to intensify, Electrical engineering became a profession in the later 19th century. Practitioners had created an electric telegraph network and the first professional electrical engineering institutions were founded in the UK. Over 50 years later, he joined the new Society of Telegraph Engineers where he was regarded by other members as the first of their cohort, Practical applications and advances in such fields created an increasing need for standardised units of measure. They led to the standardization of the units volt, ampere, coulomb, ohm, farad. This was achieved at a conference in Chicago in 1893. During these years, the study of electricity was considered to be a subfield of physics. Thats because early electrical technology was electromechanical in nature, the Technische Universität Darmstadt founded the worlds first department of electrical engineering in 1882. The first course in engineering was taught in 1883 in Cornell’s Sibley College of Mechanical Engineering. It was not until about 1885 that Cornell President Andrew Dickson White established the first Department of Electrical Engineering in the United States, in the same year, University College London founded the first chair of electrical engineering in Great Britain. Professor Mendell P. Weinbach at University of Missouri soon followed suit by establishing the engineering department in 1886

Hitachi
–
Hitachi, Ltd. is a Japanese multinational conglomerate company headquartered in Chiyoda, Tokyo, Japan. It is the parent company of the Hitachi Group and forms part of the DKB Group of companies, Hitachi is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX indices. It is ranked 38th in the 2012 Fortune Global 500 and 129th in the 2012 Forbes Global 2000, Hitachi was founded in 1910 by electrical engineer Namihei Odaira in Ibaraki Prefecture. The companys first product was Japans first 5-horsepower induction motor, initially developed for use in copper mining, odairas company soon became the domestic leader in electric motors and electric power industry infrastructure. The company began as a venture of Fusanosuke Kuharas mining company in Hitachi. Odaira moved headquarters to Tokyo in 1918, long before that, he coined the company’s toponymic name by superimposing two kanji characters, hi meaning “sun” and tachi meaning “rise”. The young companys national aspirations were conveyed by its original brand mark, world War II and its aftermath devastated the company. Many of its factories were destroyed by Allied bombing raids, and after the war, founder Odaira was removed from the company. Nevertheless, as a result of three years of negotiations, Hitachi was permitted to all but 19 of its manufacturing plants. The cost of such a production shutdown, though, compounded by a labor strike in 1950. Only the Korean War saved the company from complete collapse, Hitachi and many other struggling Japanese industrial firms benefited from defense contracts offered by the American military. Meanwhile, Hitachi went public in 1949, Hitachi America, Ltd. was established in 1959. Hitachi Europe, Ltd. was established in 1982, in March 2011, Hitachi agreed to sell its hard disk drive subsidiary, HGST, to Western Digital for a combination of cash and shares worth US$4.3 billion. Due to concerns of a duopoly of WD and Seagate Technology by the EU Commission, the transaction was completed in March 2012. The talks subsequently broke down and were suspended, the joint venture began operations in February 2014. It is a high density information storage medium utilizing laser etched/readable Fused quartz, Hitachi is taking for 2016 an estimated ¥65 billion write-off in value of a SILEX technology laser uranium enrichment joint venture with General Electric. Hitachi Consulting is a management and technology consulting firm with headquarters in Dallas, Texas. Hitachi Data Systems is an owned subsidiary of Hitachi which provides hardware, software

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

University
–
A university is an institution of higher education and research which grants academic degrees in various academic disciplines. Universities typically provide undergraduate education and postgraduate education, the word university is derived from the Latin universitas magistrorum et scholarium, which roughly means community of teachers and scholars. Universities were created in Italy and evolved from Cathedral schools for the clergy during the High Middle Ages, the original Latin word universitas refers in general to a number of persons associated into one body, a society, company, community, guild, corporation, etc. Like other guilds, they were self-regulating and determined the qualifications of their members, an important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university, the University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of academic freedom and this is now widely recognised internationally - on 18 September 1988,430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bolognas foundation. The number of universities signing the Magna Charta Universitatum continues to grow, the university is generally regarded as a formal institution that has its origin in the Medieval Christian setting. The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and it is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were founded by Kings or municipal administrations. In the early period, most new universities were founded from pre-existing schools. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries, the first universities in Europe with a form of corporate/guild structure were the University of Bologna, the University of Paris, and the University of Oxford. The students had all the power … and dominated the masters, princes and leaders of city governments perceived the potential benefits of having a scholarly expertise develop with the ability to address difficult problems and achieve desired ends. The emergence of humanism was essential to understanding of the possible utility of universities as well as the revival of interest in knowledge gained from ancient Greek texts. The rediscovery of Aristotles works–more than 3000 pages of it would eventually be translated–fuelled a spirit of inquiry into natural processes that had begun to emerge in the 12th century. Some scholars believe that these represented one of the most important document discoveries in Western intellectual history. Richard Dales, for instance, calls the discovery of Aristotles works a turning point in the history of Western thought and this became the primary mission of lecturers, and the expectation of students. The university culture developed differently in northern Europe than it did in the south, Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics, while Hippocrates, Galen, outside of these commonalities, great differences separated north and south, primarily in subject matter

Kyushu
–
Kyushu is the third biggest island of Japan and most southwesterly of its four main islands. Its alternative ancient names include Kyūkoku, Chinzei, and Tsukushi-no-shima, the historical regional name Saikaidō referred to Kyushu and its surrounding islands. In the 8th century Taihō Code reforms, Dazaifu was established as an administrative term for the region. As of 2016, Kyushu has a population of 12,970,479, the island is mountainous, and Japans most active volcano, Mt Aso at 1,591 metres, is on Kyushu. There are many signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, the island is separated from Honshu by the Kanmon Straits. The name Kyūshū comes from the nine ancient provinces of Saikaidō situated on the island, Chikuzen, Chikugo, Hizen, Higo, Buzen, Bungo, Hyūga, Osumi, excepting Oita and Miyazaki cities, the eastern seaboard shows a general decline in population. Designated cities Fukuoka Kitakyushu Kumamoto Core cities Kagoshima Ōita Nagasaki Miyazaki Naha Kurume Parts of Kyushu have a climate, particularly Miyazaki. Major agricultural products are rice, tea, tobacco, sweet potatoes, the island is noted for various types of porcelain, including Arita, Imari, Satsuma, and Karatsu. Heavy industry is concentrated in the north around Fukuoka, Kitakyushu, Nagasaki, and Oita and includes chemicals, automobiles, semiconductors, in 2010, the graduate employment rate in the region was the lowest nationwide, at 88. 9%. Besides the volcanic area of the south, there are significant mud hot springs in the part of the island, around Beppu. These springs are the site of occurrence of certain extremophile micro-organisms, the Kanmon Bridge also connects the island with Honshu. Railways on the island are operated by the Kyushu Railway Company, and Nishitetsu Railway

Radio
–
When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form, Radio systems need a transmitter to modulate some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation. Radio systems also need an antenna to convert electric currents into radio waves, an antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected, the electromagnetic wave is intercepted by a tuned receiving antenna. Radio frequencies occupy the range from a 3 kHz to 300 GHz, a radio communication system sends signals by radio. The term radio is derived from the Latin word radius, meaning spoke of a wheel, beam of light, however, this invention would not be widely adopted. The switch to radio in place of wireless took place slowly and unevenly in the English-speaking world, the United States Navy would also play a role. Although its translation of the 1906 Berlin Convention used the terms wireless telegraph and wireless telegram, the term started to become preferred by the general public in the 1920s with the introduction of broadcasting. Radio systems used for communication have the following elements, with more than 100 years of development, each process is implemented by a wide range of methods, specialised for different communications purposes. Each system contains a transmitter, This consists of a source of electrical energy, the transmitter contains a system to modulate some property of the energy produced to impress a signal on it. This modulation might be as simple as turning the energy on and off, or altering more subtle such as amplitude, frequency, phase. Amplitude modulation of a carrier wave works by varying the strength of the signal in proportion to the information being sent. For example, changes in the strength can be used to reflect the sounds to be reproduced by a speaker. It was the used for the first audio radio transmissions. Frequency modulation varies the frequency of the carrier, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal. FM has the capture effect whereby a receiver only receives the strongest signal, Digital data can be sent by shifting the carriers frequency among a set of discrete values, a technique known as frequency-shift keying. FM is commonly used at Very high frequency radio frequencies for high-fidelity broadcasts of music, analog TV sound is also broadcast using FM. Angle modulation alters the phase of the carrier wave to transmit a signal

Sanatorium
–
A sanatorium is a medical facility for long-term illness, most typically associated with treatment of tuberculosis before antibiotics. A distinction is made between sanitarium and sanatorium. In 1863, Hermann Brehmer opened the Brehmersche Heilanstalt für Lungenkranke in Görbersdorf, Silesia, patients were exposed to plentiful amounts of high altitude, fresh air, and good nutrition. Tuberculosis sanatoria became common throughout Europe from the late-19th century onward, the Adirondack Cottage Sanitarium, established in Saranac Lake, New York, in 1885, was the first such establishment in North America. According to the Saskatchewan Lung Association, when the National Anti-Tuberculosis Association was founded in 1904, its members, accordingly, they took the Latin verb root sano, meaning to heal, and adopted the new word sanatorium. Switzerland used to have many sanatoria, as health professionals believed that clean, in Finland, a series of tuberculosis sanatoria were built throughout the country in isolated forest areas during the early 1900s. The most famous was the Paimio Sanatorium, completed in 1933 and it had both sun-balconies and a rooftop terrace where the patients would lie all day either in beds or on specially designed chairs, the Paimio Chair. In Portugal, the Heliantia Sanatorium in Valadares, was used for the treatment of tuberculosis between the 1930s and 1960s. In the early 20th century, tuberculosis sanatoria became common in the United States, in the early 1900s, Arizonas sunshine and dry desert air attracted many people suffering from tuberculosis, rheumatism, asthma, and numerous other diseases. Wealthier people chose to recuperate in exclusive TB resorts, while others used their savings to make the journey to Arizona, TB camps in the desert were formed by pitching tents and building cabins. During the tuberculosis epidemic, cities in Arizona advertised the state as a place for treatment of TB. Many sanatoriums in the state of Arizona were modeled after European away-from-city resorts of the time, boasting courtyards, each sanatorium was equipped to take care of about 120 people. The greatest area for sanatoriums was in Tucson, with over 12 hotel-style facilities in the city, by 1920, Tucson had 7,000 people who had come for treatment of tuberculosis. So many people came to the West that not enough housing was available for them all, in 1910, tent cities began to pop up in different areas, one was described as a place of squalor and shunned by most citizens. Many of the infected slept in the open desert, the first tuberculosis sanatorium for blacks in the segregated South was the Piedmont Sanatorium in Burkeville, Virginia. Waverly Hills Sanatorium, a Louisville, Kentucky, tuberculosis sanatorium, was founded in 1911 and it has become a mecca for curiosity seekers who believe it is haunted. Because of its dry climate, Colorado Springs was home to several sanatoria, a. G. Holley Hospital in Lantana, Florida was the last remaining freestanding tuberculosis sanatorium in the United States until it closed on July 2,2012. In 1907, Stannington Sanatorium was open in the North East of England to treat tuberculosis in children, the sanatorium was opened using funds raised by a local charity, the Poor Childrens Holiday Association, now the regions oldest childrens charity, Children North East

Clinical trial
–
Clinical trials are experiments or observations done in clinical research. Clinical trials generate data on safety and efficacy and they are conducted only after they have received health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial – their approval does not mean that the therapy is safe or effective, only that the trial may be conducted. Clinical trials can vary in size and cost, and they can involve a research center or multiple centers. Clinical study design aims to ensure the validity and reproducibility of the results. Trials can be costly, depending on a number of factors. The sponsor may be an organization or a pharmaceutical, biotechnology or medical device company. Certain functions necessary to the trial, such as monitoring and lab work, may be managed by an outsourced partner, only 10 percent of all drugs started in human clinical trials become an approved drug. Some clinical trials involve healthy subjects with no pre-existing medical conditions, other clinical trials pertain to patients with specific health conditions who are willing to try an experimental treatment. When participants are healthy volunteers who receive financial incentives, the goals are different than when the participants are sick, during dosing periods, study subjects typically remain under supervision for one to 40 nights. Usually pilot experiments are conducted to gain insights for design of the trial to follow. There are two goals to testing medical treatments, to whether they work well enough, called efficacy or effectiveness. The benefits must outweigh the risks, in the US, the elderly constitute only 14 percent of the population, while they consume over one-third of drugs. Women, children and people with unrelated medical conditions are frequently excluded. For women, a reason for exclusion is the possibility of pregnancy. If the sponsor cannot obtain enough test subjects at one location investigators at other locations are recruited to join the study, during the trial, investigators recruit subjects with the predetermined characteristics, administer the treatment and collect data on the subjects health for a defined time period. The researchers send the data to the sponsor, who then analyzes the pooled data using statistical tests. Except for small, single-location trials, the design and objectives are specified in a document called a clinical trial protocol

Medical research
–
Biomedical research is in general simply known as medical research. It is the research, applied research, or translational research conducted to aid. An important kind of research is clinical research, which is distinguished by the involvement of patients. Other kinds of research include pre-clinical research, for example on animals. Both clinical and pre-clinical research phases exist in the pharmaceutical industrys drug development pipelines, however, only part of the clinical or pre-clinical research is oriented towards a specific pharmaceutical purpose. The need for fundamental and mechanistic understanding, diagnostics, medical devices, the most basic medical research is a rapidly evolving area that owes much to basic biology and is given names such as Human Biosciences by universities. The increased longevity of humans over the past century can be attributed to advances resulting from medical research. New, beneficial tests and treatments are expected as a result of the Human Genome Project, many challenges remain, however, including the appearance of antibiotic resistance and the obesity epidemic. Most of the research in the field is pursued by scientists, however significant contributions are made by other biologists. Medical research, done on humans, has to follow the medical ethics as sanctioned in the Declaration of Helsinki. In all cases, the research ethics has to be respected, areas tackled in the most fundamental parts of medical research include cellular and molecular biology, medical genetics, immunology, neuroscience, and psychology. Since many organisms share an evolutionary history with humans and hence common features and systems. Pre-clinical research covers research that prepares the ground for research with patients. Typically the work requires no ethical approval, is supervised by people with PhDs rather than medical doctors, the pre-clinical stage of pharmaceutical testing is covered at Phases of clinical research#Pre-clinical studies. Clinical research is carried out with patients and it is generally supervised by doctors in a medical setting such as a hospital and requires ethical approval. The clinical phase of testing is covered here Clinical trial. Research funding in many countries derives from research bodies and private organizations which distribute money for equipment, in the United Kingdom, funding bodies such as the Medical Research Council derive their assets from UK tax payers, and distribute this to institutions in a competitive manner. The Wellcome Trust is the UKs largest non-governmental source of funds for research and provides over £600 million per year in grants to scientists

Antibiotic
–
Antibiotics, also called antibacterials, are a type of antimicrobial drug used in the treatment and prevention of bacterial infections. They may either kill or inhibit the growth of bacteria, a limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the cold or influenza. Drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics, sometimes the term antibiotic is used to refer to any substance used against microbes, synonymous with antimicrobial. Some sources distinguish between antibacterial and antibiotic, antibacterials are used in soaps and disinfectants, while antibiotics are used as medicine, Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. However, their effectiveness and easy access led to overuse, especially in raising, prompting bacteria to develop resistance. All classes of antibiotics in use today were first discovered prior to the mid 1980s, substances with antibiotic properties had been used for various purposes since ancient times. Before the early 20th century, treatments for infections were based primarily on medicinal folklore, mixtures with antimicrobial properties that were used in treatments of infections were described over 2000 years ago. Many ancient cultures, including the ancient Egyptians and ancient Greeks, used specially selected mold and plant materials, more recent observations made in the laboratory of antibiosis between microorganisms led to the discovery of natural antibacterials produced by microorganisms. Louis Pasteur observed, if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics. In 1874, physician Sir William Roberts noted that cultures of the mold Penicillium glaucum that is used in the making of types of blue cheese did not display bacterial contamination. In 1876, physicist John Tyndall also contributed to this field, Louis Pasteur conducted research showing that Bacillus anthracis would not grow in the presence of the related mold Penicillium notatum. In his thesis, Duchesne proposed that bacteria and molds engage in a battle for survival. Duchesne observed that E. coli was eliminated by the fungus Penicillium glaucum when they were grown in the same culture. He also observed that when he inoculated animals with lethal doses of typhoid bacilli together with Penicillium glaucum. Unfortunately Duchesnes army service after getting his degree prevented him from doing any further research, Duchesne died of tuberculosis, a disease now treated by antibiotics. In 1928, Sir Alexander Fleming identified penicillin, a molecule produced by molds that kills or stops the growth of certain kinds of bacteria. Fleming was working on a culture of disease-causing bacteria when he noticed the spores of a mold, Penicillium chrysogenum

Streptomycin
–
Streptomycin is an antibiotic used to treat a number of bacterial infections. This includes tuberculosis, Mycobacterium avium complex, endocarditis, brucellosis, Burkholderia infection, plague, tularemia, for active tuberculosis it is often given together with isoniazid, rifampicin, and pyrazinamide. It is given by injection into a vein or muscle, common side effects include feeling like the world is spinning, vomiting, numbness of the face, fever, and rash. Use during pregnancy may result in permanent deafness in the baby, Use appears to be safe while breastfeeding. It is not recommended in people with myasthenia gravis, Streptomycin is in the aminoglycoside class of medication. It works by blocking the ability of 30S ribosomal subunits to make proteins which results in bacterial death, Streptomycin was discovered in 1943 from Streptomyces griseus. It is on the World Health Organizations List of Essential Medicines, the wholesale cost in the developing world is between 0.38 and 4.39 USD per day. In the United States a course of treatment costs more than 200 USD, infective endocarditis caused by enterococcus when the organism is not sensitive to gentamicin Tuberculosis in combination with other antibiotics. For active tuberculosis it is given together with isoniazid, rifampicin. It is not the treatment, except in medically under-served populations where the cost of more expensive treatments is prohibitive. It may be useful in cases where resistance to drugs is identified. Plague has historically been treated with it as the first-line treatment, however streptomycin is approved for this purpose only by the U. S. Food and Drug Administration. In veterinary medicine, streptomycin is the antibiotic for use against gram negative bacteria in large animals. It is commonly combined with procaine penicillin for intramuscular injection, tularemia infections have been treated mostly with streptomycin. Streptomycin is traditionally given intramuscularly, and in many nations is only licensed to be administered intramuscularly, Streptomycin also is used as a pesticide, to combat the growth of bacteria, fungi, and algae. Streptomycin controls bacterial and fungal diseases of fruit, vegetables, seed, and ornamental crops. A major use is in the control of fireblight on apple, as in medical applications, extensive use can be associated with the development of resistant strains. Streptomycin, in combination with penicillin, is used in a standard antibiotic cocktail to prevent bacterial infection in cell culture, when purifying protein from a biological extract, streptomycin sulfate is sometimes added as a means of removing nucleic acids

Electronic drum
–
An electronic drum consists of an electronic or digital sound module which produces the synthesized or sampled percussion sounds and one or more electric sensors to trigger the sounds. Like regular drums, the sensors are struck by drum sticks or by the hands, the drum pads themselves are either discs or shallow drum shells made of various materials, often with a rubber/silicone or cloth-like coated playing surface. Each pad has a sensor that generates a signal when struck. The sound signal from the module can be plugged into a keyboard amp or PA system for use in a live band performance or listened to with headphones for silent practice. Since digital drums have more popular, companies have started selling digital electronic drum files. The Acetone rhythm box was designed by Ikutaro Kakehashi, who later founded Roland Corporation Japan, as with all rhythm boxes and later drum computers, before a human feel was developed by introducing subtle variation and swing, the Acetone rhythm boxes had a metronomic, machine-like sound. In Vissers modification, the Acetone box was extended with a flat board holding 12 printed circuit boards of approximately 4 ×4 inches. The copper traces formed the touch surfaces for the sounds generated by the Acetone box, each touch pad was sensed by an electronic circuit driving high-speed Siemens computer relays he found in surplus shops. These were connected to the drum and percussion sounds of the rhythm box, although it was a crude way of playing electronic drum sounds by hand, it worked and added a human feel. Vissers approach enabled drummers to have new type of virtuosity, the unit was used in Frans Peters studio in radio city Hilversum, Netherlands. The system was over-sensitive to humidity, The circuits would be triggered by the touch pads, just breathing over them would do the job. After all wed just left the dark ages of electronic music, the first electronic drum was created in the early 1970s by Graeme Edge, drummer of The Moody Blues, in collaboration with Sussex University Professor Brian Groves. The device was used in the song Procession from the 1971 album Every Good Boy Deserves Favour, question - One of the strangest pieces was Procession, which featured the pioneering work of Graeme Edges electronic drum kit. Graeme - Id got in touch with the professor of electronics at Sussex University and we worked up an electronic drum kit, a marvellous idea. I had the panel in front of me, its old hat now. There were pieces of rubber with silver paper on the back with a coil that moved up and down inside a magnet that produced a signal. I had 5 snares across the top and then ten tom-toms and then a whole octave of bass drums underneath my feet and then four lots of 16 sequencers, there was a gap — to play a space — a tambourine, ebony stick, snare and three tom-toms. This was pre-chip days, back then you did it all with transistors, so it had something like 500 transistors

Drum machine
–
A drum machine is an electronic musical instrument designed to imitate the sound of drums, cymbals, other percussion instruments, and often basslines. Drum machines are most commonly associated with electronic music such as house music. They are usually used when session drummers are not available or if the production cannot afford the cost of a drummer. Also, many modern drum machines can also produce sounds, as well as allowing the user to compose unique drum beats. In the 2010s, most modern machines are sequencers with a sample playback or synthesizer component that specializes in the reproduction of drum timbres. The invention could produce sixteen different rhythms, each associated with a pitch, either individually or in any combination, including en masse. Received with considerable interest when it was introduced in 1932. The next generation of rhythm machines played only pre-programmed rhythms such as mambo, tango, Chamberlin Rhythmate In 1957 Californian Harry Chamberlin constructed a tape loop-based drum machine called the Chamberlin Rhythmate. It had 14 tape loops with a head that allowed playback of different tracks on each piece of tape. It contained a volume and a control and also had a separate amplifier with bass, treble, and volume controls. The tape loops were of real acoustic jazz drum kits playing different style beats, with additions to tracks such as bongos, clave, castanets. First commercial product – Wurlitzer Side Man In 1959 Wurlitzer released a drum machine called the Side Man. The Side Man was intended as an accompaniment for the Wurlitzer organ range. The Side Man offered a choice of 12 electronically generated, predefined rhythm patterns with variable tempos, the sound source was a series of vacuum tubes which created 10 preset electronic drum sounds. Combinations of these different sets of rhythms and drum sounds created popular rhythmic patterns of the day, e. g. waltzes and these combinations were selected by a rotary knob on the top of the Side Man box. The tempo of the patterns was controlled by a slider that increased the speed of rotation of the wiper arm, the Side Man had a panel of 10 buttons for manually triggering drum sounds, and a remote player to control the machine while playing from an organ keyboard. The Side Man was housed in a cabinet that contained the sound-generating circuitry. Raymond Scott In 1960, Raymond Scott constructed the Rhythm Synthesizer and, in 1963, scotts machines were used for recording his album Soothing Sounds for Baby series

A cymbal is a common percussion instrument. Often used in pairs, cymbals consist of thin, normally round plates of various alloys, the majority of cymbals are of indefinite pitch, although small disc-shaped cymbals based on ancient designs sound a definite note. Cymbals are used in ensembles ranging from the orchestra, percussion ensembles, jazz bands, heavy metal bands. Drum kits usually incorporate at least a crash, ride or crash/ride, a player of cymbals is known as a cymbalist. The word cymbal is derived from the Latin cymbalum, which is the latinisation of the Greek word κύμβαλον kymbalon, cymbal, which in turn derives from κύμβη kymbē, cup, bowl. In orchestral scores, cymbals may be indicated by the French cymbales, German Becken, Schellbecken, Tellern, or Tschinellen, Italian piatti or cinelli, many of these derive from the word for plates. Cymbals have existed since ancient times, representations of cymbals may be found in reliefs and paintings from Hittite Anatolia, Larsa, Babylon, Assyria, ancient Egypt, ancient Greece, and ancient Rome. References to cymbals also appear throughout the Bible, through many Psalms, cymbals may have been introduced to China from Central Asia in the 3rd or 4th century AD. Cymbals were employed by Turkish janissaries in the 14th century or earlier, by the 17th century, such cymbals were used in European music, and more commonly played in military bands and orchestras by the mid 18th century. Since the 19th century, some composers have called for larger roles for cymbals in musical works, and a variety of shapes, techniques. The anatomy of the plays a large part in the sound it creates. A hole is drilled in the center of the cymbal, which is used to mount the cymbal on a stand or for tying straps through. The bell, dome, or cup is the section immediately surrounding the hole. The bell produces a higher pinging pitch than the rest of the cymbal, the bow is the rest of the surface surrounding the bell. The bow is sometimes described in two areas, the ride and crash area, the ride area is the thicker section closer to the bell while the crash area is the thinner tapering section near the edge. The edge or rim is the circumference of the cymbal. Cymbals are measured by their diameter either in inches or centimeters, the size of the cymbal affects its sound, larger cymbals usually being louder and having longer sustain. The weight describes how thick the cymbal is, Cymbal weights are important to the sound they produce and how they play

Claves
–
Claves are a percussion instrument, consisting of a pair of short (about 20–30 cm, thick dowels. Traditionally they are made of wood, typically rosewood, ebony or grenadilla, in modern times they are also made of fibreglass or plastics. When struck they produce a clicking noise. Claves are sometimes hollow and carved in the middle to amplify the sound, the basic principle when playing claves is to allow at least one of them to resonate. The usual technique is to hold one lightly with the thumb and fingertips of the non-dominant hand and this forms the hand into a resonating chamber for the clave. Holding the clave on top of finger nails makes the sound more clear, the other is held by the dominant hand at one end with a firmer grip, much like how one normally holds a drumstick. With the end of this clave, the player strikes the resting clave in the center, traditionally, the striking clave is called el macho and the resting clave is called la hembra. This terminology is used even when the claves are identical, a roll can be achieved on the claves by holding one clave between the thumb and first two fingers, and then alternating pressure between the two fingers to move the clave back and forth. This clave is then placed against the resonating clave to produce a roll, claves are very important in Cuban music, such as the son and guaguancó. They are often used to play a rhythmic figure throughout a piece, known as clave. Among the better known rock recordings featuring claves are the Beatles recording And I Love Her, most notably, claves are heard in the interstitial spaces of the Night Court theme song. The Cuban Overture of George Gershwin includes claves, steve Reichs Music for Pieces of Wood is written for five pairs of claves. Palitos Clapsticks F.

Cowbell
–
A cow bell or cowbell is a bell worn by freely roaming livestock, making animals easier to locate should they wander off. Although they are referred to as cow bells, due to their extensive use with cattle. The bell and clapper are commonly crafted from iron, bronze, brass, copper, the collar used to hold the bell is traditionally made with leather and wood fibers. Most cow bells are made of thin, flat pieces of plated sheet metal, plating causes the sheet metal to have a surface which can be decorated or left plain. The craftsmanship of cow bells varies by location and culture. The cow bell is used to track of grazing animal herds such as goats, reindeer, sheep. They are mainly used in Europe, Mediterranean areas and Latin America, different bells can have specific sounds to identify important characteristics of the animals, such as age, sex, and species. Each of these bells possess unique sounds, shapes, and sizes and it is difficult to pinpoint when exactly the use of cow bells began, but the earliest examples of truly recognizable cow bells date back to the Iron Age. The use of bells in sub-Saharan African music and the Niger–Congo area is linked to the early iron-making technology spread during the Bantu migrations. The earliest archaeological evidence of bells dates back to more than 5000 years ago, during this era, there is evidence of early forms of pottery cowbells, which were likely used to track goats, sheep, and cattle. The pottery bells were replaced by metal bells. In West Asia, the first bells appeared in 1000 BC, the earliest metal bells, one found in the Taosi site, and four in the Erlitou site, are dated to about 2000 BC. Kuhschelle points to a 1410 mention in a Frankfurt archive, the OED lists 1440 as the earliest attestation of a bell-wether, in 15th-century Germany, a cow bell was worn only by the best and leading piece of livestock. The wider distribution of the worn by livestock was a gradual process of the Early Modern period. The importance of the cow bell is highlighted in Swiss folklore, as opposed to regular cast-metal bells, trychlen are made of hammered sheet metal. This results in a clanking, less sound, but at the same time results in a bell that is lighter. In Southern Germany, such cow bells are called Kuhglocke, modern-day manufacturing of cow bells continues today in Korea, Indonesia, and India, created as village handicrafts. S. In Western Europe, when the snow has melted in the spring and this event, called Alpaufzug, is celebrated in each village with a procession through the village to the high pastures

Bass drum
–
A bass drum, or kick drum, is a large drum that produces a note of low definite or indefinite pitch. Bass drums are percussion instruments and vary in size and are used in musical genres. Three major types of bass drums can be distinguished, the type usually seen or heard in orchestral, ensemble or concert band music is the orchestral, or concert bass drum. It is the largest drum of the orchestra, the kick drum, a term for a bass drum associated with a drum kit. It is struck with an attached to a pedal, usually seen on drum kits. The pitched bass drum, generally used in marching bands and drum corps and this is tuned to a specific pitch and is usually played in a set of three to six drums. A bass drum is cylindrical with the drums diameter much greater than the drums depth. There is normally a head at both ends of the cylinder. The heads may be made of skin or plastic. There is normally a means of adjusting the tension either by threaded taps or by strings, Bass drums are built in a variety of sizes, but size has little to do with the volume produced by the drum. The size chosen being based on convenience and aesthetics, music Bass drums have many synonyms and translations, such as Gran Cassa, Grosse caisse, Grosse Trommel, and Bombo. Bass drums are too large to be held and are always mounted in some way. The usual ways of mounting a bass drum are, Using a shoulder harness so that the heads are vertical, on a floor stand as part of a drum kit. The heads are always vertical when mounted in this way, in this situation, the heads may be adjusted to any position between vertical and horizontal. It is possible for the drum to have a single cymbal mounted on it. Bass drums can have a variety of strikers depending on the music, when the drum is mounted vertically, the mallet above may be held in one hand and a rute held in the other. 2 matching bass drum mallets or a double headed mallet are used for playing drum rolls, when used as part of a drum kit, a variation of the mallet described above is mounted on a pedal and called a beater. The earliest known predecessor to the drum was the Turkish davul

Multivox
–
Multivox was an American-based synthesizer company since the mid-1970s until the 1980s. Originally it was founded in the mid-1940s as the guitar and amplifier manufacturing subsidiary of Peter Sorkin Music Company and they specialized in delivering Japanese-designed and built equipment to the American market. They were criticized as having design and circuitry extremely similar to, Multivox ceased trading in the early 1980s having faded into synth history, according to the Synthmuseum. In addition to synthesizers, the company marketed several Effects pedals and these included the Big Jam series guitar effects line. As a result of the old criticism of Multivox synthesizer technology and their comparisons with Roland hardware, the main hoax was based around a Multivox MX-3000 synthesizer. These machines are quite rare although not particularly sought for by collectors, hence when a Roland MX-3000 was offered for sale much controversy surrounding the original Multivox design was stirred up. Eventually the seller admitted that the synthesizer was in fact Multivox, Multivox produced over 15 different types of synthesizers, almost all with names beginning with MX-. MX-20 - An electric piano produced from 1977 to 1978, had five presets and a bass split with independent volume control. MX-28 - The MX-28s literature says 1981 and it is very similar to MX20 except that it uses sliders instead of rotary knobs and has a Phaser instead of vibrato. It also has a built in speaker on the right side, the high/low variations of the voices is omitted, but on this machine you can actually blend the voices together. MX-30 - This model is an expansion on the MX-20 having a 61-key velocity-sensitive keyboard. MX-57/Electro-Snare - A drum synthesizer with 2VCO/VCF/VCA/SWEEP, the design is similar to the Star Instruments SYNARE3. MX-65 - Polyphonic Keyboard with 6 string sounds, mX-75 - Duophonic preset synthesizer with aftertouch effect. MX-99 - Mini Echo - An analog delay with volume tone repeat, MX-202 - String & Bass ensemble. Very similar to the Roland RS-202 synthesizer, some MX-440 might be re-badged MX-202. MX-450 - Very rare Bass Pedal, mX-880 DUO - Same as below. MX-2000 DUO - Duophonic preset synthesizer with aftertouch effect, though it has the similarity with Roland SH-2000 on design, but they are different instruments. MX-3000 - The largest and most feature-laden synthesizer of the range, includes an individual bass synth, preset synth, preset edit synth, and monophonic lead synth

Electropop
–
Electropop is a variant of synth-pop that places more emphasis on a harder, electronic sound. The genre has seen a revival of popularity and influence since the 2000s, the media in 2009 ran articles proclaiming a new era of different electropop stars and indeed, saw a rise in popularity of several electropop artists. In the Sound of 2009 poll of 130 music experts conducted for the BBC, lady Gaga had major commercial success since 2008 with her debut album The Fame. Music writer Simon Reynolds noted that Everything about Gaga came from electroclash, except the music, the second album by British singer Lily Allen released in 2009 called Its Not Me, Its You is largely electropop as opposed to her first ska album. Other female electropop acts that emerged were Ladyhawke, Kesha, Demi Lovato, Britney Spears, Selena Gomez, Elly Jackson of La Roux and Perfume. The Korean pop music scene has become dominated and influenced by electropop, particularly with boy bands and girl groups such as Super Junior, SHINee, F. Male acts that have emerged included British writer and producer Taio Cruz, who charted well in the U. S. along with one-man act Owl City, who had a U. S. number-one single, DJ Kaskade, and LMFAO. Singer Michael Angelakos of the Passion Pit said in a 2009 interview that while playing electropop was not his intention, so everything weve been put on to is electronic in nature.

Hip hop
–
Hip hop is a subculture and art movement developed by African-Americans and Latinos from the inner-city South Bronx neighbourhood in New York City in the late 1970s. Jamaican immigrant DJ Kool Herc also played a key role in developing hip hop music, at 1520 Sedgwick Avenue, Herc mixed samples of existing records and DJed percussion breaks, mixing this music with his own Jamaican-style toasting to rev up the crowd and dancers. These youths mixed these influences with existing musical styles associated with African Americans prior to the 1970s, Hip hop music became popular outside of the African-American community in the late 1980s, with the mainstream commercial success of gangsta rap. Critic Greg Tate described the hip hop movement as the only avant-garde still around, Hip hop culture has spread to both urban and suburban communities throughout the United States and subsequently the world. These elements were adapted and developed considerably, particularly as the art spread to new continents and merged with local styles in the 1990s. Sampling older culture and re-using it in a new context or a new format is called flipping in hip hop culture. Hip hop music follows in the footsteps of earlier African-American-rooted musical genres such as blues, jazz, rag-time, funk, cowboy later worked the hip hop cadence into his stage performance. The group frequently performed with artists who would refer to this new type of music by calling them hip hoppers. The name was meant as a sign of disrespect, but soon came to identify this new music. The song Rappers Delight, by The Sugarhill Gang, released in 1979, begins with the phrase I said a hip, hop the hippie the hippie to the hip hip hop, and you dont stop. Lovebug Starski, a Bronx DJ who put out a single called The Positive Life in 1981, and DJ Hollywood then began using the term when referring to this new disco rap music. Bill Alder, an independent consultant, once said, There was hardly ever a moment when rap music was underground, one of the very first so-called rap records, was a monster hit. Hip hop pioneer and South Bronx community leader Afrika Bambaataa also credits Lovebug Starski as the first to use the hip hop. Bambaataa, former leader of the Black Spades gang, also did much to popularize the term. In the 1970s, an urban movement known as Hip Hop began to develop in the South Bronx in New York City. It focused on emceeing over breakbeats, house parties and neighbourhood block party events, Hip hop music has been a powerful medium for protesting the impact of legal institutions on minorities, particularly police and prisons. Jamaican-born DJ Clive Kool Herc Cindy Campbell pioneered the use of DJing percussion breaks in hip hop music, beginning at Hercs home in a high-rise apartment at 1520 Sedgwick Avenue, the movement later spread across the entire borough. Herc created the blueprint for hip hop music and culture by building upon the Jamaican tradition of impromptu toasting, on August 11,1973 DJ Kool Herc was the DJ at his sisters back-to-school party

Standardization
–
It can also facilitate commoditization of formerly custom processes. This view includes the case of spontaneous standardization processes, to de facto standards. Standard weights and measures were developed by the Indus Valley Civilisation, weights existed in multiples of a standard weight and in categories. Technical standardisation enabled gauging devices to be used in angular measurement and measurement for construction. Uniform units of length were used in the planning of such as Lothal, Surkotada, Kalibangan, Dolavira, Harappa. The weights and measures of the Indus civilisation also reached Persia and Central Asia, Standardisation is also related to Processes. In view of large variations in units related to Civil, Electrical and other Engineering streams, engineers united to overcome the situation and this association later on gave birth to ISO in 1950. ISO stands for International Organisation for Standardisation and this voluntary organisation is solely dedicated to standardisation and makes standards related to it. Certification as per ISO norms is popular all across world, henry Maudslay developed the first industrially practical screw-cutting lathe in 1800. This allowed for the standardisation of screw thread sizes for the first time, before this, screw threads were usually made by chipping and filing. Nuts were rare, metal screws, when made at all, were usually for use in wood, metal bolts passing through wood framing to a metal fastening on the other side were usually fastened in non-threaded ways. This was an advance in workshop technology. Maudslays work, as well as the contributions of other engineers, accomplished a modest amount of industry standardization, joseph Whitworths screw thread measurements were adopted as the first national standard by companies around the country in 1841. It came to be known as the British Standard Whitworth, and was adopted in other countries. This new standard specified a 55° thread angle and a depth of 0. 640327p and a radius of 0. 137329p. The thread pitch increased with diameter in steps specified on a chart, an example of the use of the Whitworth thread is the Royal Navys Crimean War gunboats. These were the first instance of mass-production techniques being applied to marine engineering, American Unified Coarse was originally based on almost the same imperial fractions. The Unified thread angle is 60° and has flattened crests, thread pitch is the same in both systems except that the thread pitch for the 1⁄2 in bolt is 12 threads per inch in BSW versus 13 tpi in the UNC
