Francis Poulenc (1899-1963) was a French composer and pianist. His compositions include songs, solo piano works, chamber music, choral pieces, operas, ballets, and orchestral concert music. As the only son of a prosperous manufacturer, Poulenc was expected to follow his father into the family firm, and he was not allowed to enrol at a music college. Largely self-educated musically, he studied with the pianist Ricardo Viñes, who became his mentor after the composer's parents died. Poulenc also made the acquaintance of Erik Satie, under whose tutelage he became one of a group of young composers known collectively as Les Six. In his early works Poulenc became known for his high spirits and irreverence. During the 1930s a much more serious side to his nature emerged, particularly in the religious music he composed from 1936 onwards, which he alternated with his more light-hearted works.
