Art music genre, originated in 1950s
Electroacoustic music is a genre of Western art music in which composers use recording technology and audio signal processing to manipulate the timbres of acoustic sounds in the creation of pieces of music. It originated around the middle of the 20th century, following the incorporation of electronic sound production into formal compositional practice. The initial developments in electroacoustic music composition to fixed media during the 20th century are associated with the activities of the 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
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. 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.
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.
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. The beginning of the development of electronic music has been traced back to "the invention of the valve [vacuum tube] in 1906". 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"; 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.
Circuit bending
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.
