House music
–
House music is a genre of electronic music created by club DJs and music producers in Chicago in the early 1980s. Early house music was characterized by repetitive 4/4 beats, rhythms mainly provided by drum machines, off-beat hi-hat cymbals. While house displayed several characteristics similar to music, it was more electronic and minimalistic. House music became popular in Chicago clubs in 1984 and it was pioneered by figures such as Frankie Knuckles, Phuture, Kym Mazelle, and Mr. Fingers, and was associated with African-American and gay subcultures. House music quickly spread to other American cities such as Detroit, New York City, Baltimore, in the mid-to-late 1980s, house music became popular in Europe as well as major cities in South America, and Australia. Since the early to mid-1990s, house music has been infused in mainstream pop, in the late 1980s, many local Chicago house music artists suddenly found themselves presented with major label deals. House music proved to be a successful genre and a more mainstream pop-based variation grew increasingly popular. House music has also fused with other genres creating fusion subgenres, such as euro house, tech house, electro house. After enjoying significant success in the early to mid-90s, house music grew even larger during the wave of progressive house. The genre has remained popular and fused into other subgenres, for example, ghetto house, deep house. As of 2016, house music popular in both clubs and in the mainstream pop scene while retaining a foothold on underground scenes across the globe. The song structure of music songs typically involves an intro, a chorus, various verse sections, a midsection. Some songs do not have a verse, taking a part from the chorus. The drum beat is one of the important elements within the genre and is almost always provided by an electronic drum machine rather than by a human drummer playing drumkit. The drum beats of house are four on the floor, with bass drums played on every beat, House music is often based on bass-heavy loops or basslines produced by a synthesizer and/or from samples of disco or funk songs. The tempo of most house songs is between 118 and 135 beats per minute, soul music and disco influenced house music. These artists produced longer, more repetitive, and percussive arrangements of existing disco recordings, early house producers such as Frankie Knuckles created similar compositions from scratch, using samplers, synthesizers, sequencers, and drum machines. Rachel Cain, co-founder of an influential Trax Records, was involved in the burgeoning punk scene and cites industrial

Chicago
–
Chicago, officially the City of Chicago, is the third-most populous city in the United States. With over 2.7 million residents, it is the most populous city in the state of Illinois, and it is the county seat of Cook County. In 2012, Chicago was listed as a global city by the Globalization and World Cities Research Network. Chicago has the third-largest gross metropolitan product in the United States—about $640 billion according to 2015 estimates, the city has one of the worlds largest and most diversified economies with no single industry employing more than 14% of the workforce. In 2016, Chicago hosted over 54 million domestic and international visitors, landmarks in the city include Millennium Park, Navy Pier, the Magnificent Mile, Art Institute of Chicago, Museum Campus, the Willis Tower, Museum of Science and Industry, and Lincoln Park Zoo. Chicagos culture includes the arts, novels, film, theater, especially improvisational comedy. Chicago also has sports teams in each of the major professional leagues. The city has many nicknames, the best-known being the Windy City, the name Chicago is derived from a French rendering of the Native American word shikaakwa, known to botanists as Allium tricoccum, from the Miami-Illinois language. The first known reference to the site of the current city of Chicago as Checagou was by Robert de LaSalle around 1679 in a memoir, henri Joutel, in his journal of 1688, noted that the wild garlic, called chicagoua, grew abundantly in the area. In the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, the first known non-indigenous permanent settler in Chicago was Jean Baptiste Point du Sable. Du Sable was of African and French descent and arrived in the 1780s and he is commonly known as the Founder of Chicago. In 1803, the United States Army built Fort Dearborn, which was destroyed in 1812 in the Battle of Fort Dearborn, the Ottawa, Ojibwe, and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were forcibly removed from their land after the Treaty of Chicago in 1833, on August 12,1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 4,000 people, on June 15,1835, the first public land sales began with Edmund Dick Taylor as U. S. The City of Chicago was incorporated on Saturday, March 4,1837, as the site of the Chicago Portage, the city became an important transportation hub between the eastern and western United States. Chicagos first railway, Galena and Chicago Union Railroad, and the Illinois, the canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River. A flourishing economy brought residents from rural communities and immigrants from abroad, manufacturing and retail and finance sectors became dominant, influencing the American economy. The Chicago Board of Trade listed the first ever standardized exchange traded forward contracts and these issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage

Illinois
–
Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 6th most populous state and 25th largest state in terms of land area, the word Illinois comes from a French rendering of a native Algonquin word. For decades, OHare International Airport has been ranked as one of the worlds busiest airports, Illinois has long had a reputation as a bellwether both in social and cultural terms and politics. With the War of 1812 Illinois growth slowed as both Native Americans and Canadian forces often raided the American Frontier, mineral finds and timber stands also had spurred immigration—by the 1810s, the Eastern U. S. Railroads arose and matured in the 1840s, and soon carried immigrants to new homes in Illinois, as well as being a resource to ship their commodity crops out to markets. Railroads freed most of the land of Illinois and other states from the tyranny of water transport. By 1900, the growth of jobs in the northern cities and coal mining in the central and southern areas attracted a new group of immigrants. Illinois was an important manufacturing center during both world wars, the Great Migration from the South established a large community of African Americans in Chicago, who created the citys famous jazz and blues cultures. Three U. S. presidents have been elected while living in Illinois, Abraham Lincoln, Ulysses S. Grant, additionally, Ronald Reagan, whose political career was based in California, was the only U. S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official slogan, Land of Lincoln. The Abraham Lincoln Presidential Library and Museum is located in the capital of Springfield. Illinois is the spelling for the early French Catholic missionaries and explorers name for the Illinois Native Americans. American scholars previously thought the name Illinois meant man or men in the Miami-Illinois language and this etymology is not supported by the Illinois language, as the word for man is ireniwa and plural men is ireniwaki. The name Illiniwek has also said to mean tribe of superior men. The name Illinois derives from the Miami-Illinois verb irenwe·wa he speaks the regular way and this was taken into the Ojibwe language, perhaps in the Ottawa dialect, and modified into ilinwe·. The French borrowed these forms, changing the ending to spell it as -ois. The current spelling form, Illinois, began to appear in the early 1670s, the Illinois name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans, the Koster Site has been excavated and demonstrates 7,000 years of continuous habitation

Sampler (musical instrument)
–
The samples are loaded or recorded by the user or by a manufacturer. These sounds are played back by means of the sampler program itself. Because these samples are stored in digital memory, the information can be quickly accessed. A single sample may often be pitch-shifted to different pitches to produce musical scales, often samplers offer filters, effects units, modulation via low frequency oscillation and other synthesizer-like processes that allow the original sound to be modified in many different ways. Most samplers have polyphonic capabilities – they are able to more than one note at the same time. Many are also multitimbral – they can play back different sounds simultaneously, prior to computer memory-based samplers, musicians used tape replay keyboards, which store recordings on analog tape. When a key is pressed the tape head contacts the moving tape, to change sounds a new set of tapes had to be installed in the instrument. The emergence of the sampler made sampling far more practical. Bruce Haack built a digital sampler which he demonstrated on Mister Rogers Neighborhood in 1967, the home made synthesizer device included a built-in sampler which recorded, stored, played back and looped sounds controlled by switches, light sensors and human skin contact. EMS Musys system, developed by Peter Grogono, David Cockerell, the system ran on two mini-computers, Digital Equipment PDP-8s. These had 12,000 bytes of memory, backed up by a hard drive of 32k. EMS equipment was used to control the worlds first digital studio, the E-mu SP-1200 percussion sampler progressed Hip-Hop away from the drum machine sound upon its release in August 1987, ushering in the sample-based sound of the late 1980s and early 1990s. Akai pioneered many processing techniques, such as crossfade looping and time stretch to shorten or lengthen samples without affecting pitch, during the 1980s, hybrid synthesizers began to utilize short samples along with digital synthesis to create more realistic imitations of instruments than had previously been possible. Examples are the Korg M1, Roland U-110, Yamahas SY series, samplers, together with traditional Foley artists, are the mainstay of modern sound effects production. Using digital techniques various effects can be pitch-shifted and otherwise altered in ways that would have required many hours when done with tape, usually a sampler is controlled by an attached music keyboard or other external MIDI controller or source. Each note-message received by the sampler accesses a particular sample, often multiple samples are arranged across the keyboard, each assigned to a note or group of notes. Keyboard tracking allows samples to be shifted in pitch by an appropriate amount, each group of notes to which a single sample has been assigned is often called a keyzone, and the resultant set of zones is called a keymap. For example, in Fig 1, a keymap has been created four different samples

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

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

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
