Gioachino Antonio Rossini (29 February 1792 – 13 November 1868) was an Italian composer of the late Classical and early Romantic eras. He gained fame for his 39 operas, although he also wrote many songs, some chamber music and piano pieces and some sacred music. He set new standards for both comic and serious opera before retiring from large-scale composition while still in his thirties, at the height of his popularity.
Born in Pesaro to parents who were both musicians (his father a trumpeter, his mother a singer), Rossini began to compose by the age of twelve and was educated at music school in Bologna. His first opera was performed in Venice in 1810 when he was 18 years old. In 1815 he was engaged to write operas and manage theatres in Naples. In the period 1810–1823, he wrote 34 operas for the Italian stage that were performed in Venice, Milan, Ferrara, Naples and elsewhere; this productivity necessitated an almost formulaic approach for some components (such as overtures) and a certain amount of self-borrowing. During this period he produced his most popular works, including the comic operas L'italiana in Algeri, Il barbiere di Siviglia (known in English as The Barber of Seville) and La Cenerentola, which brought to a peak the opera buffa tradition he inherited from masters such as Wolfgang Amadeus Mozart, Domenico Cimarosa and Giovanni Paisiello. He also composed opera seria works such as Tancredi, Otello and Semiramide. All of these attracted admiration for their innovation in melody, harmonic and instrumental colour, and dramatic form. In 1824 he was contracted by the Opéra in Paris, for which he produced an opera to celebrate the coronation of Charles X, Il viaggio a Reims (later cannibalised for his first opera in French, Le comte Ory), revisions of two of his Italian operas, Le siège de Corinthe and Moïse, and in 1829 his last opera, Guillaume Tell.
