Jean-Baptiste Lully (] ; born Giovanni Battista Lulli ] ; 28 November 1632 – 22 March 1687) was an Italian-born French composer, instrumentalist, and dancer who spent most of his life working in the court of Louis XIV of France.
 He is considered a master of the French baroque style.
 Lully disavowed any Italian influence in French music of the period.
 He became a French subject in 1661.
Désiré-Alexandre Batton (born Paris, January 2, 1798 - died Versailles, October 15, 1855) was a French composer.
 A student of Luigi Cherubini at the Conservatoire de Paris, he composed operas and cantatas; a number of his operas were seen at the Théâtre Feydeau and the Opéra-Comique.
 In 1817 he took first place in the Prix de Rome competition for his cantata "La Mort d'Adonis".
During the course of his lifetime (1770–1827), Ludwig van Beethoven enjoyed relationships with many of his musical contemporaries.
 Beethoven was famously difficult to get along with, and the history of his relationships with contemporaries is littered with arguments, misunderstandings, and reconciliations.
 Beethoven had well-known fallings out with his one-time teacher, Joseph Haydn, with the piano virtuoso and composer Johann Nepomuk Hummel, and the German composer Carl Maria von Weber.
Leonora, ossia L’amore coniugale ("Leonora or Conjugal Love") is an opera (specifically a "dramma semiserio") in two acts by the Italian composer Ferdinando Paer.
 The libretto, by Giovanni Schmidt, is based on "Léonore ou L’Amour conjugal" (1794) by Jean-Nicolas Bouilly, which was also the source of Beethoven's "Fidelio".
 Beethoven himself owned a score of Paer's opera and it is believed to have had some influence on his work.
 "Leonora" was first performed at the Kleines Kurfürstliches Theater, Dresden on 3 October 1804 with the composer's wife singing the title role.
Giovan Leonardo Primavera (c. 1540–1585) was an Italian Renaissance composer and poet.
 Born in Barletta, he spent most of his working life in Naples, with some time in other Italian cities such as Venice, Milan, and Loreto.
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.
Titon et l'Aurore (English: "Tithonus and Aurora") is an opera in three acts and a prologue by the French composer Jean-Joseph de Mondonville which was first performed at the Académie royale de musique, Paris on 9 January 1753.
 The authorship of the libretto has been subject to debate; Mondonville's contemporaries ascribed the prologue to Antoine Houdar de la Motte and the three acts of the opera to the Abbé de La Marre.
 "Titon et l'Aurore" belongs to the genre known as the "pastorale héroïque".
 The work played an important role in the so-called Querelle des Bouffons, a dispute over the relative merits of the French and Italian operatic traditions which dominated the intellectual life of Paris in the early 1750s.
 The tremendous success of Mondonville's opera at its premiere was an important victory for the French camp (although their Italian rivals claimed that this was because they had been excluded from their seats by members of the army).
 "Titon" was one of Mondonville's most popular works and went on to enjoy several revivals during his lifetime.
Jørgen Haugen Sørensen (born 3 October 1934, Copenhagen) is one of Denmark's most eminent sculptors.
 He has spent most of his working life abroad, mainly in France and Italy, developing a style which is far removed from those of his Danish contemporaries.
This is a complete list of the operas of the Italian-born composer Luigi Cherubini (1760–1842) who spent much of his working life in France.
Beethoven's Piano Sonata No. 11 in B-flat major, Op.
 22, was composed in 1800, and published two years later.
 Beethoven regarded it as the best of his early sonatas, though some of its companions in the cycle have been at least as popular with the public.
