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 ...

Christoph Wolff

Member of Bach family

(18) (b Erfurt, bap. Nov 25, 1676; d Eisenach, June 11, 1749). Composer and organist, son of Johann Aegidius Bach (8). He studied with his father and about 1695 took up his first post, as organist at the Kaufmannskirche in Erfurt; in 1699 he went to Magdeburg, and in 1703 he replaced his kinsman (2) Johann Christoph (13) as town organist and court harpsichordist in Eisenach, a post which Johann Christoph’s son Johann Nicolaus (27) had declined. Repeated rises in salary show the esteem in which he was held, particularly in the court Kapelle, which was directed by Telemann in 1708–12.

His only extant works are instrumental; some of the organ works are in copies made by his pupils in Erfurt, who included J.G. Walther (according to Walther himself). Johann Sebastian Bach evidently valued his orchestral suites, for he had five of them copied (he himself was involved in some of the copying) for his collegium musicum in Leipzig. J.S. Bach’s obituary notice of ...

Christoph Wolff and Stephen Roe

Member of Bach family

(50) (b Leipzig, Sept 5, 1735; d London, Jan 1, 1782). Composer, youngest son of (7) Johann Sebastian Bach. As a composer he was the most versatile of J.S. Bach’s sons and the only one to write Italian operas. He was an important influence on Mozart and, with C.F. Abel, did much to establish regular public concerts in London.

It is likely that J.C. Bach’s early musical education was supervised by his father, though some instruction may have been given by Johann Elias Bach (39), who lived in the Leipzig household between 1738 and 1743 and acted as secretary to the elder Bach. Johann Christian himself assumed some secretarial duties in 1749–50, preparing music manuscripts and receipts on his father’s behalf. Christian, evidently a favourite child of Sebastian, inherited three of his father’s harpsichords. J.S. Bach’s keyboard music played an important role in his son’s development: the second book of ...

Ian Mikyska

(b Frýdek-Místek, 30 March 1980). Czech composer and guitarist. He studied singing and composition at the Ostrava Conservatory and composition at the Janáček Academy of Music and Performing Arts in Brno with Martin Smolka, with whom he completed the PhD in 2014. He also studied at the Royal Conservatory in the Hague (with Louis Andriessen and Clarence Barlow), the Matej Bel University in Bánská Bystrica, CalArts (with David Rosenboom), and the Universität für Musik und darstellende Kunst in Vienna.

His work’s penchant for drama and rhythmic drive betrays influences of both rock music and American minimalism. His harmonies are mostly dissonant, which, together with the use of fractured, grating, or fragile sounds, creates an unusual aesthetic. His work with more indeterminate types of notation, however, has led to a looser, more environmental conception of rhythm (The Book of Sand, The Book of Earth).

He has led the Dunami Ensemble since its foundation 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 ...

(Lat.: ‘against the tenor’)

The name given in the 14th and early 15th centuries to a polyphonic line composed in the same range as the Tenor. The practice of writing a part ‘against the tenor’ superseded the typical 13th-century process of adding parts above a tenor line. The first theoretical mention of the word ‘contratenor’ occurs in the treatise In arte motetorum (CS, iii, 88; 14th–15th century), and its earliest known appearance in a musical source is in a fragmentary motet manuscript of between 1315 and 1319 from the cloister of S Giorgio Maggiore, Venice (facs. in Quadrivium, ix (1968), table 1). The innovatory practice of adding a contratenor to a tenor is interestingly revealed in two motets (Vos quid admiramini/Gratissima/Gaude gloriosa and Impudenter circuivi/Virtutibus laudabilis) by Philippe de Vitry (1291–1361), which may be performed either with a conventional single-line tenor (‘tenor solus’) or with the same part ingeniously rewritten in the new manner as two lines, ‘tenor’ and ‘contratenor’....

(Lat.: ‘high [part] against the tenor’)

A line in polyphony lying just above the tenor. In the 15th century, as music came to be written in four rather than only three voices, composers approached the addition of the fourth voice by an extension of earlier compositional procedure. The most common arrangement of three voices had been superius (or cantus), tenor and Contratenor; in the new four-voice texture the composer used two contratenor parts, a contratenor bassus and a contratenor altus. The original method of writing these two voice parts is still evident in Pietro Aaron’s Il Thoscanello de la musica (1523), where ten rules set out ‘the method of composing the controbasso and the controalto, after the tenor and canto’ (bk 2, chap.21). In Italy ‘contratenorbassus’ was abbreviated to ‘bassus’, ‘controbasso’ or ‘basso’; ‘contratenor altus’ became ‘altus’, ‘controalto’, ‘contr’alto’, ‘contralto’ or ‘alto’. In France the term became Haute-contre. English usage was complicated because even in the late 16th century (by which time the word ‘contratenor’ had long been obsolete on the Continent) an alto part might also be called a meane, a contra, a counter or a ...

Rhythms in which long notes alternate with one or more short notes, so called because the long notes are usually written with the aid of the dot of addition (see Note values). Dotted rhythms are found in mensurally notated music of all periods; this article, however, deals mainly with music of the 17th and 18th centuries, in which it was customary to alter certain sorts of written rhythmic values in performance (see also Notes inégales; for notational meanings of the dot before 1600 see Notation, §III). The principal issue is the degree to which such rhythms sounded uneven, rather than the specific manner of their notation (e.g. the dot may be replaced by a rest or tie).

Dozens of contemporary theoretical and pedagogical sources indicate that the dot was ordinarily equal to one half the value of the note or rest preceding it, just as it is today. But the treatises also present various exceptions. The dot could stand for a tie (...

(b Great Barrington, MA, Feb 23, 1868; d Accra, Ghana, Aug 27, 1963). American writer and social activist. He attended Fisk University (BA 1888), Harvard University (BA 1890, PhD 1895), and the University of Berlin, cultivating music enthusiastically as a choral singer and concertgoer. Beginning with The Souls of Black Folk (1903) and continuing well into the century in essays published in The Crisis and other periodicals, Du Bois synthesized European artistic values with insightful affirmations of African American culture, including music; this approach both informed and typified the New Negro aesthetic of the early 20th century. His chapter in Souls on “The Sorrow Songs” reveals a profound understanding of the beauty and social significance of black music. Influenced here by the folk art theories of Johann Gottfried von Herder (1744–1803), Du Bois refashioned them to create a foundation for African American cultural consciousness. Elsewhere he referenced ...

Echo  

Murray Campbell and Mary Térey-Smith

The repetition of sound after a short time interval. In addition to the applications discussed below the term is used for a signal-processing device (also known as a delay) that produces a slightly delayed playback of sounds either by a tape loop or by digital delay; see Electric guitar §2 .

See also Organ stop .

Natural echoes arise from the reflection of a sound wave by a solid surface, such as a wall or cliff. For the echo to be perceived as distinct from the original sound, the extra path length travelled by the reflected sound wave must have a minimum value of around 17 metres, corresponding to a minimum time interval of 50 milliseconds between direct and reflected sounds.

The reverberant sound field in a concert hall is created by multiple reflections of sound waves. In a well-designed hall, the direct sound reaching a member of the audience is followed by a series of reflections within a time interval of around 35 milliseconds. These ‘early delayed arrivals’ are not heard as separate echoes; because of the ‘precedence effect’ they are perceived as a reinforcement of the direct sound. Subsequent reflections blend smoothly into the reverberation. A concave surface, focussing sound waves into a particular part of the hall, can give rise to an audible echo; a ‘flutter echo’ can arise from successive reflections between parallel walls....

[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 ...

Eliot Gattegno

(b Milwaukee, WI, June 27, 1960). American computer musician, sound engineer, and educator. Erbe has played an important role in American experimental and electronic music since the late 1980s. He wrote the pioneering and widely used program SoundHack, has taught computer music at key institutions, and has become one of the most highly respected sound engineers for contemporary music. Erbe studied computer science and music at the University of Illinois, Urbana-Champaign and got his start as an audio engineer by volunteering at WEFT, WPGU, and Faithful Sound Studios.

He was the technical director of the Center for Contemporary Music (CCM) at Mills College (1987–93). There he worked as a computer musician and recording engineer with composers Robert Ashley (Improvement, 1992), Larry Polansky (The Theory of Impossible Melody, 1993), James Tenney (Selected Works, 1993), and Alvin Curran (Schtyx, 1994). During this period he also developed a four-channel spatial audio processor for the NASA Ames Research Center. His research at CCM included the development of SoundHack (...

GAME

[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....

[GTCMT]

Interdisciplinary research centre for music, computing, engineering, design, and business, founded in 2008 at the Georgia Institute of Technology in Atlanta. The Center focuses on the development and deployment of transformative musical technologies, and emphasizes the impact of music technology research on scholarship, industry, and culture. In 2012 the Center had 23 faculty members.

Numerous projects have involved the development of new musical instruments, particularly mobile instruments for smartphone devices; robotic musicians that can listen to and collaborate with human performers; and novel instruments and interfaces designed for health and educational applications. GTCMT research projects have received many grants, mostly from the National Science Foundation. Two spinoff companies, ZooZ Mobile and Khush, have commercialized research results to produce mobile music creation applications.

Though the GTCMT does not have a direct educational mission, it collaborates closely with the university’s School of Music, and several of its faculty members teach courses and advise students in Georgia Tech’s Master of Science and Ph.D. programmes in music technology. The GTCMT presents concerts featuring new instruments, and related events, notably the annual Margaret Guthman Musical Instrument Competition, co-sponsored since ...

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....
