Charles_Tournemire--Cesar_Auguste_Franck

Charles Arnould Tournemire (22 January 1870 – 3 or 4 November 1939) was a French composer and organist, notable partly for his improvisations, which were often rooted in the music of Gregorian chant. His compositions include eight symphonies (one of them choral), four operas, twelve chamber works and eighteen piano solos. He is mainly remembered for his organ music, the best known being a set of pieces called L'Orgue mystique.
