Industrial music
–
Industrial music is a genre of experimental/electronic music that draws on transgressive or provocative sounds and themes. In general, the style is harsh and challenging, allMusic defines industrial as the most abrasive and aggressive fusion of rock and electronic music, initially a blend of avant-garde electronics experiments and punk provocation. The first industrial artists experimented with noise and aesthetically controversial topics, musically and visually, such as fascism, serial killers and their production was not limited to music, but included mail art, performance art, installation pieces and other art forms. Prominent industrial musicians include Throbbing Gristle, Monte Cazazza, SPK, Boyd Rice, Cabaret Voltaire, Musicians also cite writers such as William S. Burroughs, and philosophers such as Friedrich Nietzsche as influences. These artists expanded the genre by pushing it into noisier and more electronic directions, over time, its influence spread into and blended with styles including ambient and rock, all of which now fall under the post-industrial music label. Electro-industrial music is a subgenre that developed in the 1980s. These three distinct genres are often referred to as simply industrial, Industrial music drew from a broad range of predecessors. Industrial music was created originally by using mechanical and electric machinery, monroe also argues for Suicide as an influential contemporary of the industrial musicians. Groups cited as inspirational by the founders of industrial music include The Velvet Underground, Joy Division, genesis P-Orridge of Throbbing Gristle had a cassette library including recordings by the Master Musicians of Jajouka, Kraftwerk, Charles Manson, and William S. Burroughs. P-Orridge also credited 1960s rock such as The Doors, Pearls Before Swine, The Fugs, Captain Beefheart, chris Carter also enjoyed and found inspiration in Pink Floyd and Tangerine Dream. Boyd Rice was influenced by the music of 60s girl groups, Cabaret Voltaire cited Roxy Music as their initial forerunners, as well as Kraftwerks Trans-Europe Express. Cabaret Voltaire also recorded pieces reminiscent of musique concrète and composers such as Morton Subotnick, Nurse with Wound cited a long list of obscure free improvisation and Krautrock as recommended listening. 23 Skidoo borrowed from Fela Kuti and Miles Daviss On the Corner, many industrial groups, including Einstürzende Neubauten, took inspiration from world music. Many of the industrial musicians preferred to cite artists or thinkers, rather than musicians. Simon Reynolds declares that Being a Throbbing Gristle fan was like enrolling in a university course of cultural extremism, John Cage was an initial inspiration for Throbbing Gristle. SPK appreciated Jean Dubuffet, Marcel Duchamp, Jean Baudrillard, Michel Foucault, Walter Benjamin, Marshall McLuhan, Friedrich Nietzsche, Cabaret Voltaire took conceptual cues from Burroughs, J. G. Ballard, and Tristan Tzara. Whitehouse and Nurse with Wound dedicated some of their work to the Marquis de Sade, another influence on the industrial aesthetic was Lou Reeds Metal Machine Music. Pitchfork Music cites this album as inspiring, in part, much of the contemporary avant-garde music scene—noise, the album consists entirely of guitar feedback, anticipating industrials use of non-musical sounds

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

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

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

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

Aleister Crowley
–
Aleister Crowley was an English occultist, ceremonial magician, poet, painter, novelist, and mountaineer. He founded the religion of Thelema, identifying himself as the prophet entrusted with guiding humanity into the Æon of Horus in the early 20th century, a prolific writer, he published widely over the course of his life. Born to a wealthy Plymouth Brethren family in Royal Leamington Spa, Warwickshire and he was educated at the University of Cambridge, where he focused his attentions on mountaineering and poetry, resulting in several publications. Some biographers allege that here he was recruited into a British intelligence agency, in 1898 he joined the esoteric Hermetic Order of the Golden Dawn, where he was trained in ceremonial magic by Samuel Liddell MacGregor Mathers and Allan Bennett. Moving to Boleskine House by Loch Ness in Scotland, he went mountaineering in Mexico with Oscar Eckenstein, before studying Hindu and Buddhist practices in India. Announcing the start of the Æon of Horus, The Book declared that its followers should Do what thou wilt, in 1907, he and George Cecil Jones co-founded a Thelemite order, the A∴A∴, through which they propagated the religion. Thelemite groups were established in Britain, Australia, and North America, in 1920 he established the Abbey of Thelema, a religious commune in Cefalù, Sicily where he lived with various followers. His libertine lifestyle led to denunciations in the British press, and he divided the following two decades between France, Germany, and England, and continued to promote Thelema until his death. Crowley gained widespread notoriety during his lifetime, being a recreational drug experimenter, bisexual and he was denounced in the popular press as the wickedest man in the world and a Satanist. Crowley has remained an influential figure over Western esotericism and the counter-culture. In 2002, a BBC poll ranked him as the seventy-third greatest Briton of all time, Crowley was born as Edward Alexander Crowley at 30 Clarendon Square in Royal Leamington Spa, Warwickshire, on 12 October 1875. His father, Edward Crowley, was trained as an engineer and his mother, Emily Bertha Bishop, came from a Devonshire-Somerset family and had a strained relationship with her son, she described him as the Beast, a name that he revelled in. The couple had married at Londons Kensington Registry Office in November 1874. Crowleys father was particularly devout, spending his time as a preacher for the sect and reading a chapter from the Bible to his wife. Following the death of their daughter in 1880, in 1881 the Crowleys moved to Redhill. At the age of 8, Crowley was sent to H. T, habershons evangelical Christian boarding school in Hastings, and then to Ebor preparatory school in Cambridge, run by the Reverend Henry dArcy Champney, whom Crowley considered a sadist. In March 1887, when Crowley was 11, his father died of tongue cancer, Crowley described this as a turning point in his life, and he always maintained an admiration of his father, describing him as his hero and his friend. Inheriting a third of his fathers wealth, he began misbehaving at school and was punished by Champney

Gong
–
A gong is an East and South East Asian musical percussion instrument that takes the form of a flat, circular metal disc which is hit with a mallet. It originated in China and later spread to Southeast Asia, Gongs are broadly of three types. Suspended gongs are more or less flat, circular discs of metal suspended vertically by means of a cord passed through holes near to the top rim, bossed or nipple gongs have a raised centre boss and are often suspended and played horizontally. Bowl gongs are bowl-shaped, and rest on cushions and belong more to bells than gongs, Gongs are made mainly from bronze or brass but there are many other alloys in use. Gongs produce two types of sound. A gong with a flat surface vibrates in multiple modes. This category of gong is called a tam-tam to distinguish it from the bossed gongs that give a tuned note. In Indonesian gamelan ensembles, some bossed gongs are made to generate in addition a beat note in the range from about 1 to 5 Hz. The use of the gong for both these types of instrument is common. Suspended gongs are played with hammers and are of two types, flat faced discs either with or without a turned edge, and gongs with a raised centre boss. In general, the larger the gong, the larger and softer the hammer, in Western symphonic music the flat faced gongs are generally referred to as tam-tams to distinguish them from their bossed counterparts, and the term gong is reserved to the bossed type only. The gong has been a Chinese instrument for millennia and their first use may have been to signal peasant workers in from the fields as some gongs are loud enough to be heard from up to five miles away. In Japan, they are used to start the beginning of sumo wrestling contests. Large flat gongs may be primed by lightly hitting them before the stroke, greatly enhancing the sound and causing the instrument to speak sooner. Keeping this priming stroke inaudible calls for a deal of skill. The smallest suspended gongs are played with sticks, or even western-style drumsticks. Contemporary and avant-garde music, where different sounds are sought, will often use friction mallets, bass bows, rock gongs are large stones struck with smaller stones to create a metallic resonating sound. By far the most familiar to most Westerners is the chau gong or bullseye gong, large chau gongs, called tam-tams have become part of the symphony orchestra

Acoustics
–
Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of society with the most obvious being the audio. Hearing is one of the most crucial means of survival in the animal world, accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound, art, craft, science and technology have provoked one another to advance the whole, as in many other fields of knowledge. Robert Bruce Lindsays Wheel of Acoustics is a well accepted overview of the fields in acoustics. The word acoustic is derived from the Greek word ἀκουστικός, meaning of or for hearing, ready to hear and that from ἀκουστός, heard, audible, which in turn derives from the verb ἀκούω, I hear. The Latin synonym is sonic, after which the term used to be a synonym for acoustics. Frequencies above and below the range are called ultrasonic and infrasonic. If, for example, a string of a length would sound particularly harmonious with a string of twice the length. In modern parlance, if a string sounds the note C when plucked, a string twice as long will sound a C an octave lower. In one system of tuning, the tones in between are then given by 16,9 for D,8,5 for E,3,2 for F,4,3 for G,6,5 for A. Aristotle understood that sound consisted of compressions and rarefactions of air which falls upon, a very good expression of the nature of wave motion. The physical understanding of acoustical processes advanced rapidly during and after the Scientific Revolution, mainly Galileo Galilei but also Marin Mersenne, independently, discovered the complete laws of vibrating strings. Experimental measurements of the speed of sound in air were carried out successfully between 1630 and 1680 by a number of investigators, prominently Mersenne, meanwhile, Newton derived the relationship for wave velocity in solids, a cornerstone of physical acoustics. The eighteenth century saw advances in acoustics as mathematicians applied the new techniques of calculus to elaborate theories of sound wave propagation. Also in the 19th century, Wheatstone, Ohm, and Henry developed the analogy between electricity and acoustics, the twentieth century saw a burgeoning of technological applications of the large body of scientific knowledge that was by then in place. The first such application was Sabine’s groundbreaking work in architectural acoustics, Underwater acoustics was used for detecting submarines in the first World War

Drone (music)
–
In music, a drone is a harmonic or monophonic effect or accompaniment where a note or chord is continuously sounded throughout most or all of a piece. Burden also refers to a part of a song that is repeated at the end of each stanza, the term comes from the French bourdon, a staff, or a pipe made in the form of a staff. The drone does not take its name from the bee and it is a far older word, sharing an Indo-European root with the Sanskrit dhran, the Greek thren-os, and the English thrum, drum, and dream. Of all harmonic devices, it is not only the simplest, a drone effect can be achieved through a sustained sound or through repetition of a note. It most often establishes a tonality upon which the rest of the piece is built, a drone can be instrumental, vocal or both. Drone can be placed in different ranges of the texture, in the lowest part, in the highest part. The drone is most often placed upon the tonic or dominant, a drone on the same pitch as a melodic note tends to both hide that note and to bring attention to it by increasing its importance. A drone differs from a pedal tone or point in degree or quality. A pedal point may be a form of tone and thus required to resolve unlike a drone, or a pedal point may simply be considered a shorter drone. The systematic use of drones originated in instrumental music of ancient Southwest Asia, and spread north and west to Europe, east to India and it is a key component of much Australian aboriginal music through the didgeridoo. It is used in Indian music and is played with the tanpura and other Indian drone instruments like the ottu, the ektar, the dotara, the surpeti, the surmandal and the shank. Most of the types of bagpipes that exist worldwide have up to three drones, making one of the first instruments that comes to mind when speaking of drone music. In America, most forms of the African-influenced banjo contain a drone string, since the 1960s, the drone has become a prominent feature in drone music and other forms of avant-garde music. In vocal music drone is particularly widespread in traditional cultures, particularly in Europe. Drones are not uncommon in primitive music, but neither are they characteristic of it and it is also present in some isolated regions of Asia. Drone is also the term for the part of a musical instrument intended to produce the drone effects sustained pitch, different melodic Indian instruments contain a drone. For example, the sitar features three or four resonating drone strings, and Indian notes are practiced to a drone, bagpipes feature a number of drone pipes, giving the instruments their characteristic sounds. A hurdy-gurdy has one or more drone strings, the bass strings of the Slovenian drone zither also freely resonate as a drone

Resonance
–
In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency. Frequencies at which the amplitude is a relative maximum are known as the systems resonant frequencies or resonance frequencies. At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations, Resonance occurs when a system is able to store and easily transfer energy between two or more different storage modes. However, there are some losses from cycle to cycle, called damping, when damping is small, the resonant frequency is approximately equal to the natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies, resonant systems can be used to generate vibrations of a specific frequency, or pick out specific frequencies from a complex vibration containing many frequencies. Resonance occurs widely in nature, and is exploited in many manmade devices and it is the mechanism by which virtually all sine waves and vibrations are generated. Many sounds we hear, such as when hard objects of metal, glass, light and other short wavelength electromagnetic radiation is produced by resonance on an atomic scale, such as electrons in atoms. A familiar example is a swing, which acts as a pendulum. Pushing a person in a swing in time with the interval of the swing makes the swing go higher and higher. This is because the energy the swing absorbs is maximized when the match the swings natural oscillations. It may cause violent swaying motions and even catastrophic failure in improperly constructed structures including bridges, buildings, trains, avoiding resonance disasters is a major concern in every building, tower, and bridge construction project. As a countermeasure, shock mounts can be installed to absorb resonant frequencies, the Taipei 101 building relies on a 660-tonne pendulum —a tuned mass damper—to cancel resonance. Furthermore, the structure is designed to resonate at a frequency that does not typically occur, buildings in seismic zones are often constructed to take into account the oscillating frequencies of expected ground motion. Clocks keep time by mechanical resonance in a wheel, pendulum. The cadence of runners has been hypothesized to be energetically favorable due to resonance between the energy stored in the lower limb and the mass of the runner. Acoustic resonance is a branch of mechanical resonance that is concerned with the mechanical vibrations across the range of human hearing. Like mechanical resonance, acoustic resonance can result in failure of the object at resonance. The classic example of this is breaking a glass with sound at the precise resonant frequency of the glass

Noise music
–
Noise music is a category of music that is characterised by the expressive use of noise within a musical context. This type of music tends to challenge the distinction that is made in conventional musical practices between musical and non-musical sound, Noise music includes a wide range of musical styles and sound-based creative practices that feature noise as a primary aspect. Some of the music can feature acoustically or electronically generated noise, there may also be emphasis on high volume levels and lengthy, continuous pieces. More generally noise music may contain aspects such as improvisation, extended technique, cacophony, in many instances, conventional use of melody, harmony, rhythm or pulse is dispensed with. Contemporary noise music is associated with extreme volume and distortion. In the domain of experimental rock, examples include Jimi Hendrixs use of feedback, Lou Reeds Metal Machine Music, genres such as industrial, industrial techno, lo-fi music, black metal, sludge metal, and glitch music employ noise-based materials. According to Danish noise and music theorist Torben Sangild, one definition of noise in music is not possible. According to Murray Schafer there are four types of noise, unwanted noise, unmusical sound, any sound. Definitions regarding what is considered noise, relative to music, have changed over time, ben Watson, in his article Noise as Permanent Revolution, points out that Ludwig van Beethovens Grosse Fuge sounded like noise to his audience at the time. Indeed, Beethovens publishers persuaded him to remove it from its setting as the last movement of a string quartet. He did so, replacing it with a sparkling Allegro and he defines noise at different times as intrusive, unwanted, lacking skill, not being appropriate and a threatening emptiness. He traces these trends starting with 18th-century concert hall music, Hegarty contends that it is John Cages composition 433, in which an audience sits through four and a half minutes of silence, that represents the beginning of noise music proper. Writing about Japanese noise music, Hegarty suggests that it is not a genre, but it is also a genre that is multiple, Japanese noise music can come in all styles, referring to all other genres. But crucially asks the question of genre—what does it mean to be categorized, in Noise, The Political Economy of Music, Jacques Attali explores the relationship between noise music and the future of society. He indicates that noise in music is a predictor of social change, like much of modern and contemporary art, noise music takes characteristics of the perceived negative traits of noise mentioned below and uses them in aesthetic and imaginative ways. In common use, the word noise means unwanted sound or noise pollution, Noise can block, distort, or change the meaning of a message in both human and electronic communication. White noise is a signal with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency, White noise is considered analogous to white light which contains all frequencies

Field recording
–
Field recording is the term used for an audio recording produced outside a recording studio, and the term applies to recordings of both natural and human-produced sounds. Field recording of sounds, also called phonography, was originally developed as a documentary adjunct to research work in the field. With the introduction of high-quality, portable recording equipment, it has become an evocative artform in itself. In the 1970s, both processed and natural phonographic recordings, became popular, for this reason, field recordists have favoured high-quality recorders, microphones, and microphone pre-amplifiers. The history of the equipment used in this area closely tracks the development of portable audio recording technology. Field recording is typically recorded in the same format as the desired result, for instance. In contrast, a remote recording captures many microphones on multiple channels, later to be creatively modified, augmented. Field recording experienced an increase in popularity during the early 1960s, with the introduction of high-quality. The arrival of the DAT in the 1980s introduced a new level of recording fidelity with extended frequency response. In addition to these technologies, other means for field recording have included the analog cassette, the DCC. The latest generation of recorders are completely digital-based and it is also possible to use personal electronic devices, with software, to do field recording and editing. Newly developed techniques include the placement of microphones, the diffusion of captured sounds. Field recording was originally a way to document oral presentations, field recording is an important tool in bioacoustics and biomusicology, most commonly in research on bird song. Animals in the wild can display very different vocalizations from those in captivity, the use of field recordings in avant-garde, musique concrète, experimental, and, more recently, Ambient music was evident almost from the birth of recording technology. Field recordings are now a source material for a range of musical results, from contemporary musique concrète compositions to film soundtracks, video game soundtracks. The sounds recorded by any device, and then transferred to digital format, are used by musicians through their performance with MIDI-interfaced instruments. A contemporary artist with great success for his compositions is Christian Fennesz, earlier innovators who are noted for the importance and boldness of their projects are Luigi Russolo, who, in 1913, with his manifesto, Larte dei rumori, gave musical value to environmental noise. He also designed and built the Intonarumori—the first instruments for making noise, francesco Balilla Pratella utilized the Intonarumori in his opera, Laviatore Dro, which was written in close collaboration with Filippo Tommaso Marinetti
