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

Synth-pop
–
Synth-pop is a subgenre of new wave music that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument. It was prefigured in the 1960s and early 1970s by the use of synthesizers in progressive rock, electronic, art rock, disco, and particularly the Krautrock of bands like Kraftwerk. It arose as a genre in Japan and the United Kingdom in the post-punk era as part of the new wave movement of the late-1970s to the mid-1980s. In Japan, Yellow Magic Orchestras success opened the way for bands such as P-Model, Plastics. The development of polyphonic synthesizers, the definition of MIDI. This, its adoption by the acts from the New Romantic movement, together with the rise of MTV. Synth-pop is sometimes deployed interchangeably with electropop, but electropop may also denote a variant of synth-pop that places emphasis on a harder. In the late 1980s duos such as Erasure and Pet Shop Boys adopted a style that was successful on the US dance-charts. Some artists and bands were criticised for gender bending, Synth-pop was defined by its primary use of synthesizers, drum machines and sequencers, sometimes using them to replace all other instruments. Borthwick and Moy have described the genre as diverse but, many synth-pop musicians had limited musical skills, relying on the technology to produce or reproduce the music. The result was often minimalist, with grooves that were woven together from simple repeated riffs often with no harmonic progression to speak of. Early synth-pop has been described as eerie, sterile, and vaguely menacing, using droning electronics with little change in inflection, common lyrical themes of synth-pop songs were isolation, urban anomie, and feelings of being emotionally cold and hollow. Synthesizers were increasingly used to imitate the conventional and clichéd sound of orchestras, thin, treble-dominant, synthesized melodies and simple drum programmes gave way to thick, and compressed production, and a more conventional drum sound. Lyrics were generally optimistic, dealing with more traditional subject matter for pop music such as romance, escapism. According to music writer Simon Reynolds, the hallmark of 1980s synth-pop was its emotional, at times operatic singers such as Marc Almond, Alison Moyet and Annie Lennox. Because synthesizers removed the need for groups of musicians, these singers were often part of a duo where their partner played all the instrumentation. Later synth-pop saw a shift to a style influenced by other genres. Electronic musical synthesizers that could be used practically in a recording studio became available in the mid-1960s, the portable Minimoog, which allowed much easier use, particularly in live performance was widely adopted by progressive rock musicians such as Richard Wright of Pink Floyd and Rick Wakeman of Yes

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

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

Techno
–
Techno is a form of electronic dance music that emerged in Detroit, Michigan, in the United States during the mid-to-late 1980s. The first recorded use of the word techno in reference to a genre of music was in 1988. Many styles of techno now exist, but Detroit techno is seen as the foundation upon which a number of subgenres have been built. Added to this is the influence of futuristic and fictional themes relevant to life in American late capitalist society, pioneering producer Juan Atkins cites Tofflers phrase techno rebels as inspiring him to use the word techno to describe the musical style he helped to create. This unique blend of influences aligns techno with the referred to as afrofuturism. To producers such as Derrick May, the transference of spirit from the body to the machine is often a central preoccupation, in this manner, techno dance music defeats what Adorno saw as the alienating effect of mechanisation on the modern consciousness. Stylistically, techno is generally repetitive instrumental music, oftentimes produced for use in a continuous DJ set, the tempo tends to vary between approximately 120 to 150 beats per minute, depending on the style of techno. The creative use of production technology, such as drum machines, synthesizers. Many producers use retro electronic musical devices to create what they consider to be an authentic techno sound, drum machines from the 1980s such as Rolands TR-808 and TR-909 are highly prized, and software emulations of such retro technology are popular among techno producers. The Electrifying Mojo was the first radio DJ to play music by the Detroit techno producers Juan Atkins, Derrick May, Mojo refused to follow pre-established radio formats or playlists, and he promoted social and cultural awareness of the African American community. In exploring technos origins writer Kodwo Eshun maintains that Kraftwerk are to Techno what Muddy Waters is to the Rolling Stones, the authentic, the origin, the real. Juan Atkins has acknowledged that he had an enthusiasm for Kraftwerk and Giorgio Moroder, particularly Moroders work with Donna Summer. Atkins also mentions that around 1980 I had a tape of nothing but Kraftwerk, Telex, Devo, Giorgio Moroder and Gary Numan, and Id ride around in my car playing it. Regarding his initial impression of Kraftwerk, Atkins notes that they were clean, Derrick May identified the influence of Kraftwerk and other European synthesizer music in commenting that it was just classy and clean, and to us it was beautiful, like outer space. Living around Detroit, there was so little beauty, everything is an ugly mess in Detroit, and so we were attracted to this music. May has commented that he considered his music a direct continuation of the European synthesizer tradition and he also identified Japanese synthpop act Yellow Magic Orchestra, particularly member Ryuichi Sakamoto, and British band Ultravox, as influences, along with Kraftwerk. In 1980 or 1981 they met with Mojo and proposed that they provide mixes for his show, which they did end up doing the following year. These young promoters developed and nurtured the local music scene by both catering to the tastes of the local audience of young people and by marketing parties with new DJs

Drum and bass
–
Drum and bass is a genre and branch of electronic music which emerged from rave and oldschool jungle scenes in England during the early 1990s. The style is characterised by fast breakbeats with heavy bass and sub-bass lines, sampled sources. The popularity of drum and bass at its peak ran parallel to several other homegrown dance styles in the UK including big beat. Drum and bass incorporates a number of scenes and styles, a major influence on jungle and drum and bass was the original Jamaican dub and reggae sound. Another feature of the style is the syncopation of the drum tracks breakbeat. Drum and bass subgenres include breakcore, ragga jungle, hardstep, darkstep, techstep, neurofunk, ambient drum and bass, liquid funk, deep, drumfunk, funkstep, sambass, dnbnoise, from its roots in the UK, the style has established itself around the world. Drum and bass has influenced other genres like hip hop, big beat, dubstep, house, trip hop, ambient music, techno, rock. Drum and bass is dominated by a small group of record labels. The major international labels have shown very little interest in the drum. But rave music tended to feature stronger bass sounds and a faster tempo beats per minute than that of early house music and it is important to note when discussing the history of drum and bass that prior to jungle, rave music was getting faster and more experimental. Professional DJ and producer C. K. states, There was a progression as far as the speed of music is concerned, anyone buying vinyl every week from 1989 to 1992 noticed this. By 1994, jungle had begun to gain popularity and fans of the music became a more recognisable part of youth subculture. However, this developed in tandem with the positive reputation of the music as part of the wider rave scene. As the genre became more polished and sophisticated technically, it began to expand its reach from pirate radio to commercial stations. It also began to split into subgenres such as jump-up. The popularity of drum and bass at its peak ran parallel to several other homegrown dance styles in the UK including big beat. But towards the turn of the millennium its popularity was deemed to have dwindled as the UK garage style known as speed garage yielded several hit singles. London DJ/producer C. K. says, It is often forgotten by my students that a type of music called garage house existed in the late 1980s alongside hip house, acid house and other forms of house music

Nightclub
–
A nightclub is an entertainment venue and bar which serves alcoholic beverages that usually operates late into the night. Another distinction is that whereas many pubs and sports bars aim at a market, nightclubs typically aim at a niche market of music and dancing enthusiasts. The upmarket nature of nightclubs can be seen in the inclusion of VIP areas in some nightclubs, for celebrities, nightclubs are much more likely than pubs or sports bars to use bouncers to screen prospective clubgoers for entry. Some nightclub bouncers do not admit people with ripped jeans or other clothing or gang apparel as part of a dress code. The busiest nights for a nightclub are Friday and Saturday night, most clubs or club nights cater to certain music genres, such as house music or gothic rock. A nightclub may also be called a discothèque, disco, or dance club, from about 1900 to 1920, working class Americans would gather at honky tonks or juke joints to dance to music played on a piano or a jukebox. Webster Hall is credited as the first modern nightclub, being built in 1886 and starting off as a hall, originally functioning as a home for dance. During Prohibition in the United States, nightclubs went underground as illegal speakeasy bars, with Webster Hall staying open, with rumors circulating of Al Capones involvement and police bribery. With the repeal of Prohibition in February 1933, nightclubs were revived, such as New Yorks 21 Club, Copacabana, El Morocco, in Germany, possibly the first discothèque was Scotch-Club. These discothèques were also patronized by anti-Vichy youth called zazous, there were also underground discothèques in Nazi Germany patronized by anti-Nazi youth called the swing kids. In Harlem, Connies Inn and the Cotton Club were popular venues for white audiences, before 1953 and even some years thereafter, most bars and nightclubs used a jukebox or mostly live bands. The Whisky à Gogo set into place the elements of the modern post World War II discothèque-style nightclub. At the end of the 1950s, several of the bars in Soho introduced afternoon dancing. In the early 1960s, Mark Birley opened a members-only discothèque nightclub, Annabels, in Berkeley Square, in 1962, the Peppermint Lounge in New York City became popular and is the place where go-go dancing originated. However, the first rock and roll generation preferred rough and tumble bars and taverns to nightclubs, disco has its roots in the underground club scene. It brought together people from all walks of life and backgrounds and these clubs acted as safe havens for homosexual partygoers to dance in peace and away from public scrutiny. Disco allowed patrons to explore sexuality and push the envelope on the dance floor, disco clubs acted as an escape from such depressing environments and acted as the fantasy marginalized peoples could escape to forget oppression and racism. Disco clubs originally functioned as liberated party spaces and were seen as places of political statement, a smooth mix of long single records to keep people dancing all night long

Rave
–
A rave is a large dance party featuring performances by DJs and occasionally live performers playing electronic music. The music is amplified with a large, powerful sound reinforcement system, the music is accompanied by laser light shows, projected images, visual effects and fog machines. The word rave was first used in the late 1980s to describe the subculture grew out of the acid house movement. While some raves may be small parties held at nightclubs or private residences, some raves have grown to immense size, some electronic dance music festivals have features of raves, but on a large, often commercial scale. Raves may last for a time, with some events continuing for twenty-four hours. In the late 1950s in London the term rave was used to describe the wild bohemian parties of the Soho beatnik set, in 1958, Buddy Holly recorded the hit Rave On, citing the madness and frenzy of a feeling and the desire for it never to end. The word rave was used in the burgeoning mod youth culture of the early 1960s as the way to describe any wild party in general. People who were gregarious party animals were described as ravers, pop musicians such as Steve Marriott of The Small Faces and Keith Moon of The Who were self-described ravers. Presaging the words subsequent 1980s association with music, the word rave was a common term used regarding the music of mid-1960s garage rock. It was later part of the title of a music performance event held on 28 January 1967 at Londons Roundhouse titled the Million Volt Light. The event featured the only public airing of an experimental sound collage created for the occasion by Paul McCartney of The Beatles – the legendary Carnival of Light recording. With the rapid change of British pop culture from the mod era of 1963–1966 to the era of 1967 and beyond. Its use during that era would have perceived as a quaint or ironic use of bygone slang. Also during the 1970s the Chicago house movement continued to expand along with a new club - Studio 54, Studio 54 was a world-famous New York nightclub and discothèque. Founded and created by Steve Rubell and Ian Schrager in 1977, Rubell and Schrager hired Scott Bromley as architect, Ron Doud as interior designer and Brian Thompson as lighting designer. Where formerly all clubs had very dark, at Studio 54 the crowd could be lit brightly. In the late 1970s, the club was arguably the best-known nightclub in the world, the perception of the word changed again in the late 1980s when the term was revived and adopted by a new youth culture, possibly inspired by the use of the term in Jamaica. In the late 1980s, the word rave was adopted to describe the subculture grew out of the acid house movement

Alternative rock
–
Alternative rock is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s and 2000s. In this instance, the word refers to the genres distinction from mainstream rock music. The terms original meaning was broader, referring to a generation of musicians unified by their debt to either the musical style or simply the independent. Ethos of punk rock, which in the late 1970s laid the groundwork for alternative music, Alternative rock is a broad umbrella term consisting of music that differs greatly in terms of its sound, its social context, and its regional roots. Most of these subgenres had achieved minor mainstream notice and a few bands representing them, such as Hüsker Dü, with the breakthrough of Nirvana and the popularity of the grunge and Britpop movements in the 1990s, alternative rock entered the musical mainstream and many alternative bands became successful. By the end of the decade, alternative rocks mainstream prominence declined due to a number of events that caused grunge and Britpop to fade, emo attracted attention in the larger alternative rock world, and the term was applied to a variety of artists, including multi-platinum acts. Post-punk revival artists such as Modest Mouse and The Killers had commercial success in the early, before the term alternative rock came into common usage around 1990, the sort of music to which it refers was known by a variety of terms. In 1979, Terry Tolkin used the term Alternative Music to describe the groups he was writing about, in 1979 Dallas radio station KZEW had a late night new wave show entitled Rock and Roll Alternative. College rock was used in the United States to describe the music during the 1980s due to its links to the radio circuit. In the United Kingdom, dozens of small do it yourself record labels emerged as a result of the punk subculture, according to the founder of one of these labels, Cherry Red, NME and Sounds magazines published charts based on small record stores called Alternative Charts. The first national chart based on distribution called the Indie Chart was published in January 1980, at the time, the term indie was used literally to describe independently distributed records. By 1985, indie had come to mean a particular genre, or group of subgenres, at first the term referred to intentionally non–mainstream rock acts that were not influenced by heavy metal ballads, rarefied new wave and high-energy dance anthems. The use of alternative gained further exposure due to the success of Lollapalooza, for which festival founder, in the late 1990s, the definition again became more specific. Defining music as alternative is often difficult because of two conflicting applications of the word, the name alternative rock essentially serves as an umbrella term for underground music that has emerged in the wake of punk rock since the mid-1980s. Alternative bands during the 1980s generally played in clubs, recorded for indie labels. Sounds range from the gloomy soundscapes of gothic rock to the guitars of indie pop to the dirty guitars of grunge to the 1960s/1970s revivalism of Britpop. This approach to lyrics developed as a reflection of the social and economic strains in the United States and United Kingdom of the 1980s, by 1984, a majority of groups signed to independent record labels mined from a variety of rock and particularly 1960s rock influences. This represented a break from the futuristic, hyper-rational post-punk years

Dubstep
–
Dubstep is a genre of electronic dance music that originated in South London, England. It emerged in the late 1990s as a development within a lineage of related styles such as 2-step garage, dub, techno, drum and bass, broken beat, jungle, and reggae. In the United Kingdom the origins of the genre can be traced back to the growth of the Jamaican sound system party scene in the early 1980s, the music generally features sparse, syncopated drum and percussion patterns with bass lines that contain prominent sub bass frequencies. The earliest dubstep releases date back to 1998, and were featured as B-sides of 2-step garage single releases. These tracks were darker, more experimental remixes with less emphasis on vocals, a very early supporter of the sound was BBC Radio 1 DJ John Peel, who started playing it from 2003 onwards. In 2004, the last year of his show, his listeners voted Distance, Digital Mystikz, simultaneously, the genre was receiving extensive coverage in music magazines such as The Wire and online publications such as Pitchfork, with a regular feature entitled The Month In, Grime/Dubstep. Interest in dubstep grew significantly after BBC Radio 1 DJ Mary Anne Hobbs started championing the genre, towards the end of the 2000s and into the early 2010s, the genre started to become more commercially successful in the UK, with more singles and remixes entering the music charts. Music journalists and critics noticed a dubstep influence in several pop artists work. The music website Allmusic has described Dubsteps overall sound as tightly coiled productions with overwhelming bass lines and reverberant drum patterns, clipped samples, and occasional vocals. According to Simon Reynolds, Dubsteps constituents originally came from different points in the 1989—99 UK lineage, bleep n bass, jungle, techstep, Photek-style neurofunk, speed garage,2 step. Reynolds comments that the traces of pre-existing styles worked through their intrinsic sonic effects but also as signifiers, Dubsteps early roots are in the more experimental releases of UK garage producers, seeking to incorporate elements of drum and bass into the South London-based 2-step garage sound. These experiments often ended up on the B-side of a label or commercial garage release. Similar to a vocal garage hybrid – grime – the genres feel is commonly dark, tracks frequently use a minor key, other distinguishing features often found are the use of samples, a propulsive, sparse rhythm, and an almost omnipresent sub-bass. Some dubstep artists have incorporated a variety of outside influences. Dubstep rhythms are usually syncopated, and often shuffled or incorporating tuplets, the tempo is nearly always in the range of 138–142 beats per minute, with a clap or snare usually inserted every third beat in a bar. In its early stages, dubstep was often more percussive, with influences from 2‑step drum patterns. A lot of producers were experimenting with tribal drum samples, such as Loefahs early release Truly Dread. One characteristic of certain strands of dubstep is the bass, often referred to as the wub

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
