ANS  

Hugh Davies

revised by Andrei Smirnov

Photoelectric composition machine (named from the initials of Aleksandr Nikolayevich Skryabin) developed from about 1950 in Moscow by Evgeny Murzin (c1913–70). The idea for such a machine dated back to 1938, when Murzin visited the acoustician Boris Yankovsky, who had collaborated in experiments on graphic sound with Arseny Avraamov and soon afterwards worked with Evgeny Sholpo in Leningrad on his composition machine, the Variophon. The ANS was remarkably close to the concept of the Mechanical Orchestra, a sound synthesis machine proposed by Sholpo in 1917. The ANS was based on a set of optical sine wave oscillators, adjusted on fixed frequencies, forming a discrete scale, and covering the whole audible range with very small intervals between successive pitches.

World War II delayed Murzin’s work, so the first model of the ANS was not completed until 1957. It was installed in an improved form in 1959 at the Skryabin Museum in Moscow, where it became the basis of the Soviet Union’s first electronic music studio (in ...

Creation of new connections inside sound-generating electronic devices to provide sounds unintended by their original designers. A wide range of effects can be achieved, and extra tactile controls such as potentiometers, switches, photocells, and body contacts can be added to control the new effects, the most frequent modification being for pitch control. Often various ‘bends’ are found accidentally by arbitrarily connecting two different points on the circuit board. Circuit bending has attracted considerable attention among persons interested in experimental electronic music and synthesizers, and it can be achieved with limited electronics knowledge and construction skills. Because circuit bending calls for unauthorised, sometimes radical changes to the circuitry’s original pathways, it risks damaging or destroying the device being modified. Toys are often exploited for circuit bending because of their ubiquity and low cost and the small risk of electrical shock from their low voltage. Battery-operated toys such as the Texas Instruments Speak n’ Spell and the Casio SK-1 have latent sonic potential and are prime targets for tinkerers seeking such sounds inexpensively or at no cost and because they tend to ‘glitch’ easily, spewing out fragmented bits of digital speech and strange sounds. Examples of circuit-bent creations include electronic keyboards, sound modules, drum machines, effects pedals, and karaoke machines. Video bending uses these same methods to modify video-game consoles to make abstract visual patterns in addition to novel sounds....

[Compositron]

An electronic composition machine developed at the National Research Council of Canada in Ottawa from 1948 by Osmond (‘Ken’) Kendall (b Spain, 1909, of British parents), an electronics engineer at the National Film Board of Canada (NFBC). Basing his experiments on a simplified form of the optical film soundtrack and the idea of graphic sound, on which his colleague Norman McLaren was working, Kendall devised the Composertron, which employed a system for drawing sound-waveforms on a television screen with a grease pencil (probably the first use of this technique in a musical instrument); rhythm was ‘notated’ on a strip of film. The waveforms were scanned and this process controlled electronic oscillators; the resulting sounds were then recorded on magnetic tape. At the same time Kendall constructed a machine for speech synthesis using the same principle. Working models of both machines were assembled by the Canadian Marconi Co. in Montreal about ...

[Elektronmusikstudion] (Swed.: ‘electronic music studio’)

The Swedish national centre for electronic music and sound art, in Stockholm. It was preceded by a smaller studio run by the Worker’s Society of Education from 1960. EMS was established by Swedish Radio in 1964 under music director and composer Karl Birger Blomdahl (1916–68), who hired the composer and performer Knut Wiggen (b 1927) to take charge of creating the studios. In 1965 an old radio theatre studio called the klangverstan (‘sound workshop’) opened for composers. Construction of a new facility was begun, but after Blomdahl’s death EMS became independent, funded only in small part by Swedish Radio, and otherwise by Fylkingen (a society for experimental music and arts) and the Swedish Royal Academy of Music.

Wiggen envisioned EMS as both a place to produce electro-acoustic music and a research institution that would give the composer ‘the possibility of describing sounds in psychological terms’. The studio was equipped accordingly. The sound sculpture ...

[Générateur automatique de musique électronique] (Fr.: ‘automatic electronic music generator’)

Composition machine developed by the Belgian composer Léo Küpper (b Nidrum, 16 April 1935) in Brussels between 1968 and 1978. Küpper had begun experimenting with electronic music in 1959 while a student at Liège University, using two Brüel & Kjaer oscillators and a tape recorder. In 1962 he began work in Brussels at APELAC, the first Belgian electronic music studio, and joined the musical sound-effects department of the RTBF. The GAME system formed the basis of Küpper’s electronic music studio in Brussels, the Studio de Recherches et de Structurations Electroniques Auditives, which he founded in 1967. The first version of the GAME, completed in 1971, was used in concerts and installations. It consisted of 60 separate modules, using a combination of analogue and digital techniques, which could be freely selected and combined. The modules were programmed in an upright console approximately 4 × 2 metres by making a large number of patchcord interconnections, so that the surface of the console was festooned with cables. Most of the controls operated during a performance were placed in front of the console....

Mandy-Suzanne Wong

(b New Britain, CT, 1952). American video, new media, and sound artist, electroacoustic composer, and guitarist. Educated at the Eastman School of Music (BM), the Hartt School at the University of Hartford (MM), and the College-Conservatory of Music at the University of Cincinnati (DMA), Gwiazda is now professor of composition and music theory at Minnesota State University in Moorhead, Minnesota. Early in his career he composed for orchestra and electric guitar, securing performances by the New Britain Symphony, the American Dance Festival, and others.

In 1986 he turned to electroacoustic music, performing throughout the United States and Europe on sampler, guitar, and tape. In the tradition of musique concrète, Gwiazda’s collage-like pieces emphasized the musical potential inherent in environmental sounds and other so-called noises. In 1992 he began working with virtual audio: the use of sound to simulate immersive, three-dimensional spaces. His 1994 installation buzzingreynold’sdreamland uses a precise configuration of speakers to give the listener the impression of being inside a bowl of sound (Gwiazda’s sampled, vocal, and guitar sounds). ...

Interactive computer network used as an extended musical instrument, played by a San Franciso Bay–area experimental computer network band also called The Hub. The band, founded in 1985 by Tim Perkis and John Bischoff, evolved from the League of Automatic Music Composers (1978–83). The concept of The Hub is to create live music resulting from the unpredictable behaviour of the interconnected computer system. The composer/performers consider their performances a type of ‘enhanced improvisation’.

Initially The Hub provided a custom-built central ‘mailbox’ computer and made use of a MIDI network providing communication between the composer/performers’ synthesizers. With the maturation of commercial MIDI equipment, the band shifted to using the Opcode Studio V multiport MIDI interface for their hub. Since MIDI is designed to allow one player or computer to control a group of synthesizers but not to allow a network of synthesizers to interact, band member Scot Gresham-Lancaster devised a way to program the system so the Opcode Studio V could route messages among all the synthesizers in the network....

Mark Alburger

(b Harbor Beach, MI, Aug 10, 1940). American composer and performer. He began playing piano as a child and later studied with Robert Helps and Barbara Shearer. He attended the Aspen Institute in 1956, studying with Darius Milhaud, and Yale University (BA, music theory, 1962), where his principal teachers were mel Powell , lawrence k. Moss , and donald Martino . Jenks worked with Karlheinz Stockhausen at the University of California, Davis, and performed in Stockhausen’s work Ensemble at Darmstadt in 1967. He also studied composition with Andrew Imbrie and seymour Shifrin at the University of California, Berkeley (MA 1968).

Jenks became interested in electronic music through the San Francisco Tape Music Center, run by Pauline Oliveros and Ramón Sender, and thereafter associated with David Tudor and Anthony Gnazzo at Mills College. He created the performing group Deus ex Machina in collaboration with Martin Bartlett and built a large digital synthesizer called the Grand WebUrl Ensemble. Since the late 1960s much of his work has been electroacoustic. Jenks designed, contributed to, and edited ...

KIM-1  

Anne Beetem Acker

(Keyboard Input Monitor)

Computer designed by Chuck Pedal and Bill Mensch, both formerly engineers with the Motorola Corporation, and released by MOS Technology Corporation of Norristown, Pennsylvania, in 1976. It was next produced by Commodore Business Machines of Palo Alto, California, after they acquired MOS in 1977. It was originally intended as a training and development system for industrial applications. The TINY BASIC programming language could be run on the KIM-1 with extra memory, making programming far more accessible. Hence, the KIM-1 was the first microprocessor adopted by experimental composers and performers as an easier alternative to making their own custom circuitry. Jim Horton, an improvisational flutist and analogue synthesizer player, was perhaps the first to realize the musical potential of microprocessors. He purchased a KIM-1 in 1976 and mentored many of his colleagues in using it. The KIM-1 could directly generate audio or act as a controller for other electronic sound generators. Most important, it provided memory, so that the user could program a time-varying sequence of events; in other words, the program became the musical score. In ...

Portable electronic communication device. These have become robust platforms for digital audio production, composition, and music performance since the beginning of the 21st century. Recent compositions for mobile-phone ringtones might represent an emerging music genre. Since 2008, many commercial apps have transformed mobile devices into miniature synthesizers. Popular virtual-instrument programs such as Ocarina (2008) by the Smule Corporation and Band (2008) by MooCowMusic harness the phone’s numerous interfaces in various ways. Multi-point touch screens offer players the ability to manipulate graphical fingerholes, fretboards, drum pads, and keyboards, thus approximating the playing experience of acoustic wind, string, percussion, and keyboard instruments. Beyond its use in voice recording and transmission, a device’s microphone can register breath intensity, enabling users to initiate tones and alter dynamics as though playing a wind instrument.

Some mobile sound-production programs feature real-time voice manipulation, including auto-tune or pitch correction. Additional levels of musical functionality can be mapped to a phone’s accelerometer (an internal speed and direction detector). When the device is swung, shaken, or tilted, the accelerometer can trigger alterations in timbre, vibrato, pitch, and other variables. More advanced uses have been proposed. For example, a phone’s camera, acting as a real-time motion sensor, could affect many aspects of sound synthesis and sequencing; and the GPS (global positioning system) indicator has the potential to take location markers from other phones across the planet and turn those data into sonic information....
