Maurice Duruflé
Duruflé only left a few of his works for publication.  His two important organ works are the Suite, op. 5  which has a famous Toccata as last movement, and his Prelude and Fugue sur le nom d'Alain.  His Requiem remains a favourite work for choirs.  Duruflé’s music uses Gregorian plainchant, modal harmonies and polyphonic writing.  He was a great admirer of the music of Louis Vierne and Charles Tournemire and he made transcriptions of some of their improvisations.
