CARPENTER, JOHN ALDEN

born Feb. 28, 1876, Park Ridge, Ill., U.S. died April 26, 1951, Chicago American composer who was prominent in the 1920s and was one of the earliest to use jazz rhythms in orchestral music. Carpenter studied at Harvard University under the conservative, German-influenced composer John Knowles Paine but then joined his father's shipping supply firm, of which he was vice president (190936). In 1906 he studied music under Sir Edward Elgar. After 1936 he concentrated solely on composition. Basically a conservative composer influenced by the French Impressionists, he incorporated jazz rhythms into his Concertino for Piano and Orchestra (1917) and into his ballets Krazy Kat (1922) and Skyscrapers (1926); the last was later made into a symphonic piece. His humorous orchestral suite Adventures in a Perambulator also won considerable popularity.
