(b Antwerp, 8 June 1923; d Antwerp, 3 Feb. 1993). Belgian composer. He studied at the Paris Conservatoire with Messiaen and Milhaud. In 1951 he composed a Sonata for two pianos, a pioneering exercise in total serialism; at the Darmstadt summer courses it made a significant impact on Stockhausen. Goeyvaerts later experimented with tape composition, the combination of instruments with electronics, and the psychology of performance and perception. From 1970 he worked at IPEM in Ghent, and from 1974 to 1987 he was a producer for Belgian Flemish Radio. His opera Aquarius was performed in Rotterdam in 1990.
