Déodat de Séverac (1872 – 1921) was a French composer, of aristocratic background. He was profoundly influenced by the musical tradition of his native Languedoc, and noted for his vocal and choral music, which include settings of verse in Provençal and Catalan. His compositions for solo piano were often titled as pictorial evocations. His masterpiece is the suite Cerdaña, filled with the local color of Languedoc. His motet Tantum ergo is also still sung on occasion. He left his native Toulouse to study in Paris, under Vincent d'Indy at the Schola Cantorum. He returned to the south of France, where he spent the rest of his rather short life. He was an organ student of Guilmant, and composed two suites for the organ - Petite Suite Scholastica (pub. 1913) and Suite pour Orgue, dedicated to Guilmant, and composed c. 1900.
