Marie François Maurice Emmanuel (2 May 1862 – 14 December 1938) was a French composer, teacher of Messiaen and musicologist born in Bar-sur-Aube, a small town in the Champagne-Ardenne region of northeastern France.
He wrote over 70 opus numbers, then destroyed over half of them. Only 30 or so survive....among them some music for organ.
An exact contemporary of Claude Debussy, he was right from the outset an authentic creator of the avant-garde and was thrown out of Delibes' class because of his early modal compositions.
Emmanuel pursued a notable academic career. He wrote a treatise in 1895 on the music of Ancient Greece, for which he earned a doctorate in 1896.
In 1904 he became choirmaster at the church of Sainte-Clotilde, assisted by Émile Poillot, during the tenure of organist Charles Tournemire, serving until 1907. Emmanuel's interests included folksong, Oriental music, birdsong and exotic modes. Probably his most often performed music now are his six sonatines for solo piano, which demonstrate his eclectic academic interests. The first of the sonatines draws on the music of Burgundy, while the second incorporates birdsong, the third uses a Burgundian folk tune in its finale, and the fourth is subtitled en divers modes hindous ("in various Hindu modes").
