William Tell (opera) in the context of William Tell

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.

French opera is both the art of opera in France and opera in the French language. It is one of Europe's most important operatic traditions, containing works by composers of the stature of Rameau, Berlioz, Gounod, Bizet, Massenet, Debussy, Ravel, Poulenc and Messiaen. Many foreign-born composers have played a part in the French tradition, including Lully, Gluck, Salieri, Cherubini, Spontini, Meyerbeer, Rossini, Donizetti, Verdi and Offenbach.

French opera began at the court of Louis XIV with Jean-Baptiste Lully's Cadmus et Hermione (1673), although there had been various experiments with the form before that, most notably Pomone by Robert Cambert. Lully and his librettist Quinault created tragédie en musique, a form in which dance music and choral writing were particularly prominent. Lully's most important successor was Rameau. After Rameau's death, Christoph Willibald Gluck was persuaded to produce six operas for the Paris Opera in the 1770s. They show the influence of Rameau, but simplified and with greater focus on the drama. At the same time, by the middle of the 18th century another genre was gaining popularity in France: opéra comique, in which arias alternated with spoken dialogue. By the 1820s, Gluckian influence in France had given way to a taste for the operas of Rossini. Rossini's Guillaume Tell helped found the new genre of Grand opera, a form whose most famous exponent was Giacomo Meyerbeer. Lighter opéra comique also enjoyed tremendous success in the hands of Boieldieu, Auber, Hérold and Adam. In this climate, the operas of Hector Berlioz struggled to gain a hearing. Berlioz's epic masterpiece Les Troyens, the culmination of the Gluckian tradition, was not given a full performance for almost a hundred years after it was written.

The Dance Class is an 1874 oil painting on canvas by the French artist Edgar Degas. It is in the collection of the Metropolitan Museum of Art, in New York.

The painting and its companion work in the Musée d'Orsay, Paris, are amongst the most ambitious works by Degas on the theme of ballet. The imaginary scene depicts a dance class being held under the supervision of Jules Perrot, a famous ballet master, in the old Paris Opera, which had actually burnt down the previous year.The poster on the wall for Rossini's Guillaume Tell is a tribute to the operatic singer Jean-Baptiste Faure, who had commissioned the work.

William Tell (German: Wilhelm Tell, German pronunciation: [ˈvɪlhɛlm ˈtɛl] ) is a drama written by Friedrich Schiller in 1804. The story focuses on the legendary Swiss marksman William Tell as part of the greater Swiss struggle for independence from the Habsburg Empire in the early 14th century. Gioachino Rossini's four-act opera Guillaume Tell was written to a French adaptation of Schiller's play.
