Gioachino Rossini (1792–1868) was an Italian composer known for his 39 operas, although he also wrote many songs, some chamber music and piano pieces, and some sacred music. In the period 1810–1823 he wrote his most popular works including the comic operas L'italiana in Algeri, Il barbiere di Siviglia (The Barber of Seville) and La Cenerentola, building on the traditions of masters such as Domenico Cimarosa. He also composed opera seria works such as Otello, Tancredi and Semiramide. All of these show 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 cannibalized for Le comte Ory, and in 1829 his last opera, Guillaume Tell (William Tell). He retired from large-scale composition while still in his thirties, at the height of his popularity.
