Electronic music



Electronic music is music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general a distinction can be made between sound produced using electromechanical means and that produced using electronic technology.[1]  Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the Theremin, sound synthesizer, and computer.[2]

Electronic music was once associated almost exclusively with Western art music but from the late 1960s on the availability of affordable music technology meant that music produced using electronic means became increasingly common in the popular domain.[3]  Today electronic music includes many varieties and ranges from experimental art music to popular forms such as electronic dance music.

In 1876, engineer Elisha Gray filed a patent for the electromechanical oscillator. This "Musical Telegraph," evolved out of his experiments with telephone technology and is the earliest extant patent for producing electronic sound. This oscillator was expanded on by Alexander Graham Bell for the early telephone.[citation needed]  By 1878, Thomas A. Edison further developed the oscillator for the phonograph, which also used cylinders similar to Scott's device. Although cylinders continued in use for some time, Emile Berliner developed the disc phonograph in 1887.[5] Lee De Forest's 1906 invention, the triode audion tube, later had a profound effect on electronic music. It was the first thermionic valve, or vacuum tube, and led to circuits that could create and amplify audio signals, broadcast radio waves, compute values, and perform many other functions.

Before electronic music, there was a growing desire for composers to use emerging technologies for musical purposes. Several instruments were created that employed electromechanical designs and they paved the way for the later emergence of electronic instruments. An electromechanical instrument called the Telharmonium (sometimes Teleharmonium or Dynamophone) was developed by Thaddeus Cahill in the years 1898–1912. However, simple inconvenience hindered the adoption of the Telharmonium, due to its immense size. One early electronic instrument often mentioned may be the Theremin, invented by Professor Léon Theremin circa 1919–1920.[6]  Other early electronic instruments include the Audion Piano invented in 1915 by Lee De Forestwho was inventor of triode audion as mentioned above,[7] <sup class="reference" id="cite_ref-8" style="line-height:1em;unicode-bidi:-webkit-isolate;">[8]  the Croix Sonore, invented in 1926 by Nikolai Obukhov, and the Ondes Martenot, which was most famously used in the Turangalîla-Symphonie by Olivier Messiaen as well as other works by him. The Ondes Martenot was also used by other, primarily French, composers such as Andre Jolivet.<sup class="reference" id="cite_ref-9" style="line-height:1em;unicode-bidi:-webkit-isolate;">[9] ===Sketch of a New Esthetic of Music<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main article: Ferruccio Busoni<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">In 1907, just a year after the invention of the triode audion, Ferruccio Busoni published Sketch of a New Esthetic of Music, which discussed the use of electrical and other new sound sources in future music. He wrote of the future of microtonal scales in music, made possible by Cahill's Dynamophone: "Only a long and careful series of experiments, and a continued training of the ear, can render this unfamiliar material approachable and plastic for the coming generation, and for Art."<sup class="reference" id="cite_ref-10" style="line-height:1em;unicode-bidi:-webkit-isolate;">[10]

And we have talked of them for a long time!

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:1.5em;">We have formulated rules, stated principles, laid down laws;—we apply laws made for maturity to a child that knows nothing of responsibility!

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:1.5em;">Young as it is, this child, we already recognize that it possesses one radiant attribute which signalizes it beyond all its elder sisters. And the lawgivers will not see this marvelous attribute, lest their laws should be thrown to the winds. This child—it floats on air! It touches not the earth with its feet. It knows no law of gravitation. It is well nigh incorporeal. Its material is transparent. It is sonorous air. It is almost Nature herself. It is—free!

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:1.5em;">But freedom is something that mankind have never wholly comprehended, never realized to the full. They can neither recognize or acknowledge it.

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:1.5em;">They disavow the mission of this child; they hang weights upon it. This buoyant creature must walk decently, like anybody else. It may scarcely be allowed to leap—when it were its joy to follow the line of the rainbow, and to break sunbeams with the clouds.<sup class="reference" id="cite_ref-11" style="line-height:1em;unicode-bidi:-webkit-isolate;">[11] <p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">Through this writing, as well as personal contact, Busoni had a profound effect on many musicians and composers, perhaps most notably on his pupil, Edgard Varèse, who said: <p style="line-height:1.5em;">Together we used to discuss what direction the music of the future would, or rather, should take and could not take as long as the straitjacket of the tempered system. He deplored that his own keyboard instrument had conditioned our ears to accept only an infinitesimal part of the infinite gradations of sounds in nature. He was very much interested in the electrical instruments we began to hear about, and I remember particularly one he had read of called the Dynamophone. All through his writings one finds over and over again predictions about the music of the future which have since come true. In fact, there is hardly a development that he did not foresee, as for instance in this extraordinary prophecy: 'I almost think that in the new great music, machines will also be necessary and will be assigned a share in it. Perhaps industry, too, will bring forth her share in the artistic ascent.'<sup class="reference" id="cite_ref-12" style="line-height:1em;unicode-bidi:-webkit-isolate;">[12] ===Futurists<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main article: Futurism (music)<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">In Italy, the Futurists approached the changing musical aesthetic from a different angle. A major thrust of the Futurist philosophy was to value "noise," and to place artistic and expressive value on sounds that had previously not been considered even remotely musical. Balilla Pratella's "Technical Manifesto of Futurist Music" (1911) states that their credo is: "To present the musical soul of the masses, of the great factories, of the railways, of the transatlantic liners, of the battleships, of the automobiles and airplanes. To add to the great central themes of the musical poem the domain of the machine and the victorious kingdom of Electricity."<sup class="reference" id="cite_ref-13" style="line-height:1em;unicode-bidi:-webkit-isolate;">[13]

In 1914, he held the first "art-of-noises" concert in Milan on April 21. This used his Intonarumori, described by Russolo as "acoustical noise-instruments, whose sounds (howls, roars, shuffles, gurgles, etc.) were hand-activated and projected by horns and megaphones."<sup class="reference" id="cite_ref-tvnpyt_14-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[14]  In June, similar concerts were held in Paris. ===The 1920s to 1930s<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Further information: Electronic musical instrument and Léon ThereminSee also: Graphical sound, Trautonium, and Harald Bode<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">This decade brought a wealth of early electronic instruments and the first compositions for electronic instruments. The first instrument, the Etherophone, was created by Léon Theremin (born Lev Termen) between 1919 and 1920 in Leningrad, though it was eventually renamed the Theremin. This led to the first compositions for electronic instruments, as opposed to noisemakers and re-purposed machines. In 1929, Joseph Schillinger composed First Airphonic Suite for Theremin and Orchestra, premièred with the Cleveland Orchestra with Leon Theremin as soloist.

A. O'Neill developed a recording device that used magnetically coated ribbon. However, this was a commercial failure. Two years later, Laurens Hammond established his company for the manufacture of electronic instruments. He went on to produce the Hammond organ, which was based on the principles of the Telharmonium, along with other developments including early reverberation units.<sup class="reference" id="cite_ref-16" style="line-height:1em;unicode-bidi:-webkit-isolate;">[16] Hammond (along with John Hanert and C. N. Williams) would also go on to invent another electronic instrument, the Novachord, which Hammond's company manufactured from 1939–1942.<sup class="reference" id="cite_ref-17" style="line-height:1em;unicode-bidi:-webkit-isolate;">[17]

It extended the 1941 'K4' Magnetophone frequency curve to 10 kHz and improved the dynamic range up to 60 dB,<sup class="reference" id="cite_ref-engel-weber_21-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[21]  surpassing all known recording systems at that time.<sup class="reference" id="cite_ref-22" style="line-height:1em;unicode-bidi:-webkit-isolate;">[22]

Audio tape was relatively cheap and very reliable, and its fidelity of reproduction was better than any audio medium to date. Most importantly, unlike discs, it offered the same plasticity of use as film. Tape can be slowed down, sped up or even run backwards during recording or playback, with often startling effect. It can be physically edited in much the same way as film, allowing for unwanted sections of a recording to be seamlessly removed or replaced; likewise, segments of tape from other sources can be edited in. Tape can also be joined to form endless loops that continually play repeated patterns of pre-recorded material. Audio amplification and mixing equipment further expanded tape's capabilities as a production medium, allowing multiple pre-taped recordings (and/or live sounds, speech or music) to be mixed together and simultaneously recorded onto another tape with relatively little loss of fidelity. Another unforeseen windfall was that tape recorders can be relatively easily modified to become echo machines that produce complex, controllable, high-quality echo and reverberation effects (most of which would be practically impossible to achieve by mechanical means).

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">The spread of tape recorders eventually led to the development of electroacoustic tape music. The first known example was composed in 1944 by Halim El-Dabh, a student at Cairo, Egypt.<sup class="reference" id="cite_ref-wire_2007_27-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[27]  He recorded the sounds of an ancient zaarceremony using a cumbersome wire recorder and at the Middle East Radio studios processed the material using reverberation, echo, voltage controls, and re-recording. The resulting work was entitled The Expression of Zaar and it was presented in 1944 at an art gallery event in Cairo. While his initial experiments in tape based composition were not widely known outside of Egypt at the time, El-Dabh is also notable for his later work in electronic music at the Columbia-Princeton Electronic Music Center in the late 1950s.<sup class="reference" id="cite_ref-28" style="line-height:1em;unicode-bidi:-webkit-isolate;">[28] ===Musique concrète<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main article: Musique concrèteSee also: Acousmatic music<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">It wasn't long<sup class="noprint Inline-Template" style="line-height:1em;white-space:nowrap;">[when?]  before composers in Paris also began using the tape recorder to develop a new technique for composition called musique concrète. This technique involved editing together recorded fragments of natural and industrial sounds.<sup class="reference" id="cite_ref-lebrecht1_29-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[29]  The first pieces of musique concrète in Paris were assembled by Pierre Schaeffer, who went on to collaborate with Pierre Henry.

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">On 5 October 1948, Radiodiffusion Française (RDF) broadcast composer Pierre Schaeffer's Etude aux chemins de fer. This was the first "movement" of Cinq études de bruits, and marked the beginning of studio realizations<sup class="reference" id="cite_ref-30" style="line-height:1em;unicode-bidi:-webkit-isolate;">[30]  and musique concrète (or acousmatic art). Schaeffer employed a disk-cutting lathe, four turntables, a four-channel mixer, filters, an echo chamber, and a mobile recording unit. Not long after this, Henry began collaborating with Schaeffer, a partnership that would have profound and lasting effects on the direction of electronic music. Another associate of Schaeffer, Edgard Varèse, began work on Déserts, a work for chamber orchestra and tape. The tape parts were created at Pierre Schaeffer's studio, and were later revised at Columbia University.

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">In 1950, Schaeffer gave the first public (non-broadcast) concert of musique concrète at the Ecole Normale de Musique de Paris. "Schaeffer used a PA system, several turntables, and mixers. The performance did not go well, as creating live montages with turntables had never been done before."<sup class="reference" id="cite_ref-31" style="line-height:1em;unicode-bidi:-webkit-isolate;">[31]  Later that same year, Pierre Henry collaborated with Schaeffer on Symphonie pour un homme seul (1950) the first major work of musique concrete. In Paris in 1951, in what was to become an important worldwide trend, RTF established the first studio for the production of electronic music. Also in 1951, Schaeffer and Henry produced an opera, Orpheus, for concrete sounds and voices. ===Elektronische Musik<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Karlheinz Stockhausen in the Electronic Music Studio of WDR, Cologne, in 1991<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">Karlheinz Stockhausen worked briefly in Schaeffer's studio in 1952, and afterward for many years at the WDR Cologne's Studio for Electronic Music.

In his 1949 thesis Elektronische Klangerzeugung: Elektronische Musik und Synthetische Sprache, Meyer-Eppler conceived the idea to synthesize music entirely from electronically produced signals; in this way, elektronische Musik was sharply differentiated from French musique concrète, which used sounds recorded from acoustical sources.<sup class="reference" id="cite_ref-33" style="line-height:1em;unicode-bidi:-webkit-isolate;">[33]

Several years after the end of World War II, musicians in Japan began experimenting with electronic music, resulting in some of the most dedicated efforts due to institutional sponsorship enabling composers to experiment with the latest audio recording and processing equipment. These efforts represented an infusion of Asian music into the emerging genre and would eventually pave the way for Japan's domination in the development of music technology several decades later.<sup class="reference" id="cite_ref-holmes_106_37-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[37]

In 1949, Shibata wrote about his concept of "a musical instrument with very high performance" that can "synthesize any kind of sound waves" and is "operated very easily," predicting that with such an instrument, "the music scene will be changed drastically."<sup class="reference" id="cite_ref-39" style="line-height:1em;unicode-bidi:-webkit-isolate;">[39]  The same year, Sony developed the magnetic tape recorder G-Type,<sup class="reference" id="cite_ref-fujii_66_40-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[40]  which became a popular recording device in courtrooms and government offices, leading to Sony releasing the H-Type for home use by 1951.<sup class="reference" id="cite_ref-holmes_106_37-1" style="line-height:1em;unicode-bidi:-webkit-isolate;">[37]

It included musicians such as Toru Takemitsu, Kuniharu Akiyama, and Joji Yuasa, and was supported by Sony, which offered them access to the latest audio technology, hired Takemitsu to compose electronic tape music to demonstrate their tape recorders, and sponsored concerts.<sup class="reference" id="cite_ref-41" style="line-height:1em;unicode-bidi:-webkit-isolate;">[41]  The first electronic tape music from the group were "Toraware no Onna" ("Imprisoned Woman") and "Piece B", completed in 1951 by Kuniharu Akiyama.<sup class="reference" id="cite_ref-holmes_107_42-0" style="line-height:1em;unicode-bidi:-webkit-isolate;">[42]  Many of the electroacoustic tape pieces they produced were usually used as incidental music for radio, film, and theatre. They also held concerts such as 1953's Experimental Workshop, 5th Exhibition, which employed an 'auto-slide', a machine developed by Sony that made it possible to synchronize a slide show with a soundtrack recorded on tape; they used the same device to produce the concert's tape music at the Sony studio. The concert, along with the experimental electroacoustic tape music they produced, anticipated the introduction of musique concrète in Japan later that year.<sup class="reference" id="cite_ref-43" style="line-height:1em;unicode-bidi:-webkit-isolate;">[43]  Beyond the Jikken Kobo, several other composers such as Yasushi Akutagawa, Saburo Tominaga and Shiro Fukai were also experimenting with producingradiophonic tape music between 1952 and 1953.<sup class="reference" id="cite_ref-fujii_66_40-1" style="line-height:1em;unicode-bidi:-webkit-isolate;">[40]

Musicians associated with the studio included Toshiro Mayuzumi, Minao Shibata, Joji Yuasa, Toshi Ichiyanagi, and Toru Takemitsu. The studio's first electronic compositions were complete in 1955, including Mayuzumi's 5-minute pieces "Studie I: Music for Sine Wave by Proportion of Prime Number", "Music for Modulated Wave by Proportion of Prime Number" and "Invention for Square Wave and Sawtooth Wave" produced using the studio's various tone-generating capabilities, and Shibata's 20-minute stereo piece "Musique Concrète for Stereophonic Broadcast".<sup class="reference" id="cite_ref-47" style="line-height:1em;unicode-bidi:-webkit-isolate;">[47]

There, the two collaborated on various pieces. Luening described the event: "Equipped with earphones and a flute, I began developing my first tape-recorder composition. Both of us were fluent improvisors and the medium fired our imaginations."<sup class="reference" id="cite_ref-urajla_53-1" style="line-height:1em;unicode-bidi:-webkit-isolate;">[53]  They played some early pieces informally at a party, where "a number of composers almost solemnly congratulated us saying, 'This is it' ('it' meaning the music of the future)."<sup class="reference" id="cite_ref-urajla_53-2" style="line-height:1em;unicode-bidi:-webkit-isolate;">[53]

Three major works were premiered that year: Varèse's Déserts, for chamber ensemble and tape sounds, and two works by Luening and Ussachevsky: Rhapsodic Variations for the Louisville Symphony and A Poem in Cycles and Bells, both for orchestra and tape. Because he had been working at Schaeffer's studio, the tape part for Varèse's work contains much more concrete sounds than electronic.

El-Dabh's Leiyla and the Poet, released as part of the album Columbia-Princeton Electronic Music Center in 1961, would be cited as a strong influence by a number of musicians, ranging from Neil Rolnick, Charles Amirkhanian and Alice Shields to rock musicians Frank Zappa and The West Coast Pop Art Experimental Band.<sup class="reference" id="cite_ref-60" style="line-height:1em;unicode-bidi:-webkit-isolate;">[60] ===Stochastic music<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main articles: Iannis Xenakis and Stochastic music<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">An important new development was the advent of computers for the purpose of composing music, as opposed to manipulating or creating sounds. Iannis Xenakis began what is called musique stochastique, or stochastic music, which is a composing method that uses mathematical probability systems. Different probability algorithms were used to create a piece under a set of parameters. Xenakis used computers to compose pieces like ST/4 for string quartet and ST/48for orchestra (both 1962),<sup class="reference" id="cite_ref-61" style="line-height:1em;unicode-bidi:-webkit-isolate;">[61]  Morsima-Amorsima, ST/10, and Atrées. He developed the computer system UPIC for translating graphical images into musical results and composed Mycènes Alpha (1978) with it. ===Mid-to-late 1950s<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === <p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">In 1954, Stockhausen composed his Elektronische Studie II—the first electronic piece to be published as a score. In 1955, more experimental and electronic studios began to appear. Notable were the creation of the Studio de Fonologia (already mentioned), a studio at the NHK in Tokyo founded by Toshiro Mayuzumi, and the Phillips studio at Eindhoven, the Netherlands, which moved to the University of Utrecht as the Institute of Sonology in 1960.

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">The world's first computer to play music was CSIRAC, which was designed and built by Trevor Pearcey and Maston Beard. Mathematician Geoff Hill programmed the CSIRAC to play popular musical melodies from the very early 1950s. In 1951 it publicly played the Colonel Bogey March, of which no known recordings exist.<sup class="reference" id="cite_ref-63" style="line-height:1em;unicode-bidi:-webkit-isolate;">[63]  However, CSIRAC played standard repertoire and was not used to extend musical thinking or composition practice. CSIRAC was never recorded, but the music played was accurately reconstructed (reference 12). The oldest known recordings of computer generated music were played by the Ferranti Mark 1 computer, a commercial version of the Baby Machine from theUniversity of Manchester in the autumn of 1951. The music program was written by Christopher Strachey.

<p style="margin-top:0.4em;margin-bottom:0.5em;line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">The impact of computers continued in 1956. Lejaren Hiller and Leonard Isaacson composed Illiac Suite for string quartet, the first complete work of computer-assisted composition using algorithmic composition. "... Hiller postulated that a computer could be taught the rules of a particular style and then called on to compose accordingly."<sup class="reference" id="cite_ref-64" style="line-height:1em;unicode-bidi:-webkit-isolate;">[64]  Later developments included the work of Max Mathews at Bell Laboratories, who developed the influential MUSIC I program. In 1957, MUSIC, one of the first computer programs to play electronic music, was created by Max Mathews at Bell Laboratories. Vocoder technology was also a major development in this early era. In 1956, Stockhausen composedGesang der Jünglinge, the first major work of the Cologne studio, based on a text from the Book of Daniel. An important technological development of that year was the invention of the Clavivox synthesizer by Raymond Scott with subassembly by Robert Moog.

That same year, Mauricio Kagel, an Argentinecomposer, composed Transición II. The work was realized at the WDR studio in Cologne. Two musicians perform on a piano, one in the traditional manner, the other playing on the strings, frame, and case. Two other performers use tape to unite the presentation of live sounds with the future of prerecorded materials from later on and its past of recordings made earlier in the performance. ==Expansion: 1960s<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] == See also: Synthesizer, Harald Bode, Modular synthesizer, Buchla, and Moog Music<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">These were fertile years for electronic music—not just for academia, but for independent artists as synthesizer technology became more accessible. By this time, a strong community of composers and musicians working with new sounds and instruments was established and growing. 1960 witnessed the composition of Luening's Gargoyles for violin and tape as well as the premiere of Stockhausen's Kontakte for electronic sounds, piano, and percussion. This piece existed in two versions—one for 4-channel tape, and the other for tape with human performers. "In Kontakte, Stockhausen abandoned traditional musical form based on linear development and dramatic climax.

On a Guggenheim at the time, I extended this concept to real-time score-following with automatic synchronized accompaniment, and over the next two years Larry and I gave numerous demonstrations of the computer as a chamber musician, playing Handel flute sonatas, Boulez's Sonatine for flute and piano and by 1984 my own Synapse II for flute and computer—the first piece ever composed expressly for such a setup. A major challenge was finding the right software constructs to support highly sensitive and responsive accompaniment. All of this was pre-MIDI, but the results were impressive even though heavy doses of tempo rubato would continually surprise my Synthetic Performer. In 1985 we solved the tempo rubato problem by incorporating learning from rehearsals (each time you played this way the machine would get better). We were also now tracking violin, since our brilliant, young flautist had contracted a fatal cancer. Moreover, this version used a new standard called MIDI, and here I was ably assisted by former student Miller Puckette, whose initial concepts for this task he later expanded into a program called MAX.<sup class="reference" id="cite_ref-111" style="line-height:1em;unicode-bidi:-webkit-isolate;">[111] ===Chiptunes<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main article: ChiptuneSee also: Video game music<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">The new availability of low-cost home computers in the 80s and 90s led to the rise of chiptunes. Chiptunes, chipmusic, or chip music is music written in sound formats where many of the sound textures are synthesized or sequenced in real time by a computer or video game console sound chip, sometimes including sample-based synthesis and low bit sample playback. Many chip music devices featured synthesizers in tandem with low rate sample playback.<sup class="Template-Fact" style="line-height:1em;white-space:nowrap;">[citation needed]  The characteristic lo-fi sound of chip music was initially the result of early sound cards' technical limitations; however, the sound has since become sought after in its own right. ==Late 1980s to 1990s<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] == ===Rise of dance music<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;padding-right:0.25em;unicode-bidi:-webkit-isolate;">[edit] === Main article: Electronic dance musicSee also: Italo disco<p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">In the late 1980s, dance music records made using only electronic instruments became increasingly popular.<sup class="Template-Fact" style="line-height:1em;white-space:nowrap;">[citation needed]  The trend has continued to the present day with modern nightclubs worldwide regularly playing electronic dance music.

Based on a novel scheme of harmonization devised by Eustache, the software analyzes the tonal melodic function of incoming notes, and instantaneously performs an orchestrated harmonization of the melody. The software was originally designed for performance by Eustache on Yamaha WX7 wind controller, and was used in his composition Tetelestai, premiered in Irvine, California in March 1999.<sup class="reference" id="cite_ref-112" style="line-height:1em;unicode-bidi:-webkit-isolate;">[112] <p style="line-height:19.200000762939453px;color:rgb(0,0,0);font-family:sans-serif;font-size:13px;">Other recent developments included the Tod Machover (MIT and IRCAM) composition Begin Again Again for "hypercello", an interactive system of sensors measuring physical movements of the cellist.

Emphasizing spontaneity and randomness, the techniques of circuit bending have been commonly associated with noise music, though many more conventional contemporary musicians and musical groups have been known to experiment with "bent" instruments. Circuit bending usually involves dismantling the machine and adding components such as switches and potentiometers that alter the circuit. With the revived interest for analogue synthesizer circuit bending became a cheap solution for many experimental musicians to create their own individual analogue sound generators. Nowadays many schematics can be found to built noise generators such as the Atari Punk Console or the Dub Siren as well as simple modifications for children toys such as the famous Speak & Spells that are often modified by circuit benders. Reed Ghazala is commonly referred to as the 'Father of Circuit Bending' due to his initial discoveries with the Speak & Spell, and has held apprenticeships and workshops since beginning his work.
