Gioacchino Rossini was an Italian composer who wrote 39 operas as well as sacred music, chamber music, songs, and some instrumental and piano pieces. His best-known operas include the Italian comedies Il barbiere di Siviglia (The Barber of Seville) and La Cenerentola and the French-language epics Moïse et Pharaon and Guillaume Tell (William Tell). A tendency for inspired, song-like melodies is evident throughout his scores, which led to the nickname "The Italian Mozart." Until his retirement in 1829, Rossini had been the most popular opera composer in history.
