Dahl, Ingolf , distinguished German-born American pianist, conductor, pedagogue, and composer of German-Swedish descent; b. Hamburg, June 9, 1912; d. Frutigen, near Bern, Aug. 6, 1970. After composition training with Jarnach at the Cologne Hochschule für Musik (1930–32), he went to Zürich and studied musicology at the Univ. and conducting with Andreae at the Cons. (1932–36). In 1938 he emigrated to the U.S., becoming a naturalized American citizen in 1943. In 1944 he received additional training from Boulanger. In 1945 he joined the faculty of the Univ. of Southern Calif, in Los Angeles, where he also conducted its sym. orch. until 1958, and again in 1968–69. During the summers from 1952 to 1957, he oversaw his own Tanglewood Study Group at the Berkshire Music Center. During the summers from 1964 to 1966, he served as director and conductor of the Ojai Festival. In 1954 and 1968 he held Guggenheim fellowships, and in 1964 he received the Alice M. Ditson Award. As a performer, Dahl was an active champion of contemporary music. He became associated with Stravinsky, who influenced him in his direction as a composer. With his Piano Quartet (1957), Dahl adopted serial techniques that he utilized inventively in such works as his Sinfonietta for Concert Band (1961) and his Aria Sinfonica (1965).
