Maurice Duruflé was a French composer and organist, who wrote chamber music and works for choir, organ and orchestra. He was also organist of Saint-Étienne-du-Mont in Paris, professor of harmony at the Paris Conservatory, and formed a famous organ duo with his wife Marie-Madeleine Chevalier.
Duruflé's works are reminiscent of impressionism, and are characterized by clarity, poetry and a clear design. Besides, Gregorian chant is an important source of inspiration, which is evident from the use of medieval modes. For his most famous work, the Requiem, Duruflé took the Gregorian mass of the dead as his point of departure, and combined it with the structure and optimism of the Requiem of Fauré.
