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.
