Document 4: Idomeneo: Idomeneo, re di Creta ossia Ilia e Idamante (Italian for "Idomeneus, King of Crete, or, Ilia and Idamante"; usually referred to simply as Idomeneo, K. 366) is an Italian language opera seria by Wolfgang Amadeus Mozart. The libretto was adapted by Giambattista Varesco from a French text by Antoine Danchet, which had been set to music by André Campra as "Idoménée" in 1712. Mozart and Varesco were commissioned in 1780 by Karl Theodor, Elector of Bavaria for a court carnival. He probably chose the subject, though it might have been Mozart. The work premiered on 29 January 1781 at the Cuvilliés Theatre in Munich, Germany.
Document 5: Il Bellerofonte: Il Bellerofonte is an 18th-century Italian opera in three acts by the Czech composer Josef Mysliveček. It conforms to the serious type (opera seria) that was typically set in the distant past. The libretto, based on the Greek legend of Bellerophon, was written by Giuseppe Bonecchi. The work was dedicated to King Ferdinand I of the Two Sicilies and was first performed at the Teatro San Carlo in Naples on 20 January 1767, the birthday of his father, King Charles III of Spain. The cast featured two stellar singers of the time, Caterina Gabrielli and Anton Raaff, in the leading roles. The opera was only the composer's second one, and the first that permitted him the opportunity to write music for first-rate vocal artists. The production was highly successful, indeed responsible for a meteoric rise in his reputation as an operatic composer. From the time of the premiere of "Bellerofonte" until his death in 1781, Mysliveček succeeded in having more new "opere serie" brought into production than any other composer in Europe. During the same time span, he also had more new operas staged at the Teatro San Carlo in Naples than any other composer.
Document 6: Luigi Cherubini: Luigi Cherubini (] ; 8 or 14 September 1760 – 15 March 1842) was an Italian composer who spent most of his working life in France. His most significant compositions are operas and sacred music. Beethoven regarded Cherubini as the greatest of his contemporaries.
Document 7: Anacréon (Cherubini): Anacréon, ou L'amour fugitif is an opera-ballet in two acts by Luigi Cherubini with a French libretto by C. R. Mendouze. It was premiered on 4 October 1803 by the Paris Opéra at the Salle Montansier. The choreography was by Pierre-Gabriel Gardel. The work proved to be a complete failure, ending its run on 1 January 1804 after only seven performances. The subject matter, a love affair of the Ancient Greek poet Anacreon, was completely alien to the spirit of the time. One critic complained that in his protagonist Cherubini had represented ""un vieux debauché déguisé en héros d'opéra"" ("an old debauchee disguised as an opera hero").
Document 8: Overture in G major (Cherubini): The Overture in G major by Luigi Cherubini (1760-1842) is an orchestral work written for concert use in early 1815. It is unusual among Cherubini's overtures in that his other, better known overtures (such as those to "Anacreon", "Médée", "Les deux journées" and "Ali Baba"), were intended to introduce stage works. Although born in Italy Cherubini had been living in France since 1784, and had earned world fame through a series of operas composed for the Paris stage. In the first decade of the nineteenth century the vogue for his dramatic works began to wane, and he turned increasingly to sacred music.
Document 9: Prix de Rome cantatas (Berlioz): The French composer Hector Berlioz made four attempts at winning the Prix de Rome music prize, finally succeeding in 1830. As part of the competition, he had to write a cantata to a text set by the examiners. Berlioz's efforts to win the prize are described at length in his "Memoirs". He regarded it as the first stage in his struggle against the musical conservatism represented by the judges, who included established composers such as Luigi Cherubini, François-Adrien Boieldieu and Henri Montan Berton. Berlioz's stay in Italy as a result of winning the prize also had a great influence on later works such as "Benvenuto Cellini" and "Harold en Italie". The composer subsequently destroyed the scores of two cantatas ("Orphée" and "Sardanapale") almost completely and reused music from all four of them in later works. There was a revival of interest in the cantatas in the late 20th century, particularly "La mort de Cléopâtre", which has become a favourite showcase for the soprano and mezzo-soprano voice.
Document 10: Christoph Willibald Gluck: Christoph Willibald (Ritter von) Gluck (] ; 2 July 1714 – 15 November 1787) was a composer of Italian and French opera in the early classical period. Born in the Upper Palatinate (now part of Germany) and raised in Bohemia, he gained prominence at the Habsburg court at Vienna, where he brought about the practical reform of opera's dramaturgical practices that many intellectuals had been campaigning for over the years. With a series of radical new works in the 1760s, among them "Orfeo ed Euridice" and "Alceste", he broke the stranglehold that Metastasian "opera seria" had enjoyed for much of the century.
Document 11: Pomone (opera): Pomone ("Pomona") is a pastoral opera in a prologue and five acts by Robert Cambert with a libretto by Pierre Perrin. It has been described as "effectively the first French opera." It was first performed in Paris at the Jeu de Paume de la Bouteille theatre belonging to Cambert and Perrin's Académie d'Opéra on 3 March 1671. The production had ballets choreographed by Des Brosses and sets and machinery designed by Alexandre de Rieux, marquis de Sourdéac. The novelty of the work drew large audiences and the opera enjoyed 146 performances over the eight months of its run. The score of "Pomone" has only partially survived.
Document 12: Iphigénie en Tauride (Piccinni): Iphigénie en Tauride ("Iphigeneia in Tauris") is a tragédie lyrique in four acts by Niccolò Piccinni, which was first performed on 23 January 1781 by the Académie royale de musique (the Paris Opéra) in the second Salle du Palais-Royal. The opera's libretto, by Alphonse du Congé Dubreuil, is based on a play of the same name by Claude Guimond de La Touche, although the ultimate source was the tragedy "Iphigeneia in Tauris" by Euripides.
Document 13: Épicure (opera): Épicure ("Epicurus") is an opera in three acts with music by the composers Étienne Méhul and Luigi Cherubini. The libretto is by Charles-Albert Demoustier. It was first performed at the Opéra-Comique, Paris on 14 March 1800. It was a complete failure, enjoying only three performances. For the third and final performance on 20 March the opera was reduced from three acts to two. Cherubini wrote the overture, the first act and half of the third; Méhul the second act and the rest of the third.
Document 14: Démophoon: Démophoon (sometimes spelt Démophon) is an opera by the composer Luigi Cherubini, first performed at the Académie Royale de Musique (the Paris Opera) on 2 December 1788. It takes the form of a "tragédie lyrique" in three acts. The libretto, by Jean-François Marmontel, is based on "Demofoonte" by Metastasio.
Document 15: Giulio Sabino: The opera, staged in six or seven European countries at the end of the 18th century, was the subject of a parody in Antonio Salieri's 1786 work "Prima la musica e poi le parole".
