French composer and pianist. A student of Ravel and member of Les Apaches, he was influenced by travels to India and the East. Ravel's "La vallée des cloches" from Miroirs was dedicated to Delage. His best known piece is Quatre poemes hindous (1912-13). His Ragamalika (1912-22), based on the classical music of India, is also significant in that it calls for prepared piano; the score specifies that a piece of cardboard be placed under the strings of the B-flat in the second line of the bass clef to dampen the sound, imitating the sound of an Indian drum.
