'''Gioachino Antonio Rossini'''"Though 'Gioacchino' is the familiar spelling of the name, Rossini himself more usually adopted the spelling 'Gioachino'. This is now the accepted spelling of his first name" per Osborne, 1986 Master Musicians Series, p. xv; Osborne, 1998, pp. 56-67; ''Baker's Biographical Dictionary of Musicians'', and most Rossini scholars (including the [ Fondazione G. Rossini] and the [ Center for Italian Opera Studies at the University of Chicago])Radiciotti 1927 -- 1929, p. 8: "Giovacchino Antonio Rossini" appears on the baptismal certificate (; 29 February 179213 November 1868) 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'' ''(Cinderella)'', 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.Fisher 2005, p. ?
