MUSIC
Rossini was well known for being remarkably productive, completing an average of two operas per year for 19 years, and in some years writing as many as four. Musicologists believe that, true to form, the music for Il barbiere di Siviglia was composed in just under three weeks,[9] although the famous overture was actually recycled from two earlier Rossini operas, Aureliano in Palmira and Elizabeth, Queen of England and thus contains none of the thematic material in Il barbiere di Siviglia itself.[10]
