(French: "concrete music"), experimental technique of musical composition using recorded sounds as raw material. The technique was developed about 1948 by the French composer Pierre Schaeffer and his associates at the Studio d'Essai ("Experimental Studio") of the French radio system. The fundamental principle of musique concrete lies in the assemblage of various natural sounds recorded on tape (or, originally, on disks) to produce a montage of sound. During the preparation of such a composition, the sounds selected and recorded may be modified in any way desired-played backward, cut short or extended, subjected to echo-chamber effects, varied in pitch and intensity, and so on. The finished composition thus represents the combination of varied auditory experiences into an artistic unity
