Vincent D'Indy (văNsäN´ dăNdē´), 1851–1931, French composer. D'Indy was a pupil of César Franck. In 1894, Charles Bordes, Guilmant, and d'Indy founded the Schola Cantorum, Paris, of which d'Indy was composition teacher and, from 1911 until his death, director. His methods of teaching are largely embodied in Cours de composition musicale (3 vol., 1903; rev. ed. 1950), of which he was joint author. D'Indy wrote 13 operas, including Le Chant de la cloche (1879–83); several music dramas; Symphony on a French Mountain Air for piano and orchestra (1886); the symphonic variations Istar (1896); songs; chamber music; piano works; and three additional symphonies.
