Morceau de Concert Camille Saint-Saëns contributed voluminously to the French concertante literature. He wrote five piano concertos, three violin concertos, two cello concertos, and about twenty smaller concertante works for soloist and orchestra. Among these works are three Morceau de Concerts, one each for harp, horn, and violin and orchestra. His Morceau de Concert for Horn (opus 94) was written as a version for horn and piano in October 1887, and then completed in a version for horn and orchestra one month later.
