(b Quebec City, 22 Sept. 1929; d Sherbrooke, PQ, 1 Nov. 1986). Canadian composer. He studied composition with Claude Champagne in Montreal (1946–50) and attended courses with Messiaen in Paris (1951–2). On his return to Montreal in 1954, he organized concerts of new music and performed Schoenberg's piano music. Acknowledging early influences including Messiaen and Webern, he developed a musical language and style similar to that of Boulez, using serialism. Garant was the first Canadian composer to combine magnetic tape and instruments (Nucléogame, 1955) and was noted for his experimental music; his aleatory pieces include Pièces pour quatuor à cordes. He spent scholarship years in Basle (studying conducting with Boulez), Bali, and Rome. In 1966 he founded the Société de Musique Contemporaine du Québec (SMCQ), directing it from its inception until his death. He was appointed professor at the University of Montreal in 1967. Among his most important works are Phrases II (1968), Offrande II (1970), Cage d'oiseau (1962), and Chant d'amours (1975). He was also active as a conductor.
