(b Paris, 5 Feb. 1929; d 22 Aug. 2005). French composer. He studied at the Versailles Conservatoire (1946–8), with Honegger and Alfred Cortot at the École Normale de Musique, Paris (1948–50), with Messiaen (1953), and with Varèse in New York (1954). In 1958, with Pierre Schaeffer, he set up the Groupe de Recherches Musicales, which he briefly directed. His output is divided evenly between works for electronic resources and those for more conventional forces. Presque rien no. 1 (1970) is a compilation of everyday sounds recorded in a Yugoslav village, and in other works too he has used the tape recorder to explore the place of music and sound generally in life. Works for live performance include the orchestral Histoire du plaisir et de la désolation (1979–81) and two music-theatre pieces: Journal intime (Paris, 1982) and Cahier du soir (Strasbourg, 1994).
