Mario Davidovsky (1934–2019) was an Argentine-American composer whose music explored the interaction of acoustic instruments and electronic sound. Born in Médanos, Argentina, he studied at the University of Buenos Aires before attending Tanglewood in 1958 at Aaron Copland’s invitation. He moved to New York in 1960 to work at the Columbia-Princeton Electronic Music Center, later becoming its director. His Synchronisms No. 6 for piano and electronic sounds received the 1971 Pulitzer Prize. Davidovsky also composed extensively for acoustic ensembles, bringing his experience of electronic timbre to chamber, orchestral and vocal works. He taught at Columbia and Harvard, where he founded the Harvard Computer Music Center, and led the Composers Conference for many years.
