Electroacoustic music

(Redirected from Electro-acoustic music)

Electroacoustic music is a genre of popular and Western art music in which composers use technology to manipulate the timbres of acoustic sounds, sometimes by using audio signal processing, such as reverb or harmonizing, on acoustical instruments.[1] It originated around the middle of the 20th century, following the incorporation of electric sound production into compositional practice. The initial developments in electroacoustic music composition to fixed media during the 20th century are associated with the activities of the Groupe de recherches musicales [fr] at the ORTF in Paris, the home of musique concrète, the Studio for Electronic Music in Cologne, where the focus was on the composition of elektronische Musik, and the Columbia-Princeton Electronic Music Center in New York City, where tape music, electronic music, and computer music were all explored. Practical electronic music instruments began to appear in the early 20th century.

Tape music

See also: Musique concrète

Tape music is an integral part of musique concrète, which uses the tape recorder as its central musical source. The music can utilise pre-recorded sound fragments and the creation of loops, which can be altered and manipulated through techniques such as editing and playback speed manipulation.[2] The work of Halim El-Dabh is perhaps the earliest example of tape (or, in this case, Wire recording) music. El-Dabh's The Expression of Zaar, first presented in Cairo, Egypt, in 1944, was an early work using musique concrète–like techniques similar to those developed in Paris during the same period. El-Dabh would later become more famous for his work at the Columbia-Princeton Electronic Music Center, where in 1959 he composed the influential piece Leiyla and the Poet.[3]

Composer John Cage's assembly of the Williams Mix serves as an example of the rigors of tape music. First, Cage created a 192-page score. Over the course of a year, 600 sounds were assembled and recorded. Cut tape segments for each occurrence of each sound were accumulated on the score. Then the cut segments were spliced to one of eight tapes, work finished on January 16, 1953. The premiere performance (realization) of the 4'15" work was given on March 21, 1953, at the University of Illinois, Urbana.[4]

Electronic music

In Cologne, elektronische Musik, pioneered in 1949–51 by the composer Herbert Eimert and the physicist Werner Meyer-Eppler, was based solely on electronically generated (synthetic) sounds, particularly sine waves.[5][6][7] The beginning of the development of electronic music has been traced back to "the invention of the valve [vacuum tube] in 1906".[5] The precise control afforded by the studio allowed for what Eimert considered to be the subjection of everything, "to the last element of the single note", to serial permutation, "resulting in a completely new way of composing sound";[8] in the studio, serial operations could be applied to elements such as timbre and dynamics. The common link between the two schools is that the music is recorded and performed through loudspeakers, without a human performer. The majority of electroacoustic pieces use a combination of recorded sound and synthesized or processed sounds, and the schism between Schaeffer's and Eimert's approaches has been overcome, the first major example being Karlheinz Stockhausen's Gesang der Jünglinge of 1955–56.[9][10]

Circuit bending

edit

Circuit bending is the creative short-circuiting of low voltage, battery-powered electronic audio devices such as guitar effects, children's toys and small synthesizers to create new musical instruments and sound generators. 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.[11]

Examples of notable works

Electronic and electroacoustic instruments

Important centers of research and composition can be found around the world, and there are numerous conferences and festivals which present electroacoustic music, notably the International Computer Music Conference, the international conference on New Interfaces for Musical Expression, the Electroacoustic Music Studies Conference, and the Ars Electronica Festival (Linz, Austria).

A number of national associations promote the art form, notably the Canadian Electroacoustic Community (CEC) in Canada, the Society for Electro-Acoustic Music in the United States (SEAMUS) in the US, the Australasian Computer Music Association in Australia and New Zealand, and Sound and Music (previously the Sonic Arts Network) in the UK. The Computer Music Journal and Organised Sound are the two most important peer-reviewed journals dedicated to electroacoustic studies, while several national associations produce print and electronic publications.

Festivals

edit
See also: List of electronic music festivals and Category:Electroacoustic music festivals

There have been a number of festivals that feature electroacoustic music. Early festivals, such as Donaueschingen Festival, founded in 1921, were some of the first to include electroacoustic instruments and pieces. This was followed by ONCE Festival of New Music in the 1950s, and since the 1960s, there has been a growth of festivals that focus exclusively on electroacoustic music.

Conferences and symposiums

edit

Alongside paper presentations, workshops and seminars, many of these events also feature concert performances or sound installations created by those attending or which are related to the theme of the conference / symposium.
