after world war i his continuing devotion to the symphonic poem and the large orchestra at a period when neoclassicism and small ensembles were more fashionable may have discouraged performance and acceptance of his works. his compositions include the four symphonic poems and three orchestral songs making up "livre de la jungle" after rudyard kipling; many other symphonic poems including "le buisson ardent" after romain rolland (this is a diptych of two orchestral poems, performable separately) and "le docteur fabricius" after a novel by his uncle charles dollfus; three string quartets; five symphonies including a "seven stars symphony" inspired by hollywood; sonatas for flute, oboe, clarinet, bassoon, horn, violin, viola and cello, and much other chamber music; many songs, over two hundred opus numbers in all; and a vast number of monodies, fugal studies, chorale harmonizations and other educational pieces. many works remain unpublished, however.
