Gioachino Antonio Rossini (] ; 29 February 179213 November 1868) was an Italian composer who wrote 39 operas, as well as some sacred music, songs, chamber music and piano pieces.
Baroque music ( or ) is a style of Western art music composed from approximately 1600 to 1750.
 This era followed the Renaissance music era, and was followed in turn by the Classical era.
 Baroque music forms a major portion of the "classical music" canon, being nowadays widely studied, performed, and listened to.
 Key composers of the Baroque era include Johann Sebastian Bach, Antonio Vivaldi, George Frideric Handel, Claudio Monteverdi, Domenico Scarlatti, Alessandro Scarlatti, Henry Purcell, Georg Philipp Telemann, Jean-Baptiste Lully, Jean-Philippe Rameau, Marc-Antoine Charpentier, Arcangelo Corelli, Tomaso Albinoni, François Couperin, Giuseppe Tartini, Heinrich Schütz, Giovanni Battista Pergolesi, Dieterich Buxtehude, and Johann Pachelbel.
Il Pompeo is a dramma per musica in three acts by composer Alessandro Scarlatti.
 Written in 1682 when Scarlatti was 22 years old, it was his fourth opera and first dramatic work on a serious and grand subject.
 The opera uses an Italian language libretto by Nicolò Minato which had previously been used by Francesco Cavalli for his 1666 opera "Pompeo Magno".
 The work premiered at the Teatro di Palazzo Colonna in Rome on 25 January 1683.
L'honestà negli amori is a dramma per musica in 3 acts by composer Alessandro Scarlatti.
 Written in 1679-1680 when Scarlatti was 19 years old, it was his second opera.
 The opera uses an Italian language libretto that was written by either D F Bernini or Domenico Filippo Contini.
 The work premiered at the Teatro di Palazzo Bernini in Rome on 3 February 1680.
 The opera was performed again in 1682 in Acquaviva delle Fonti at the Palazzo De Mari with "Acquaviva laureata" a serenata composed by Giovanni Cesare Netti.
Giuseppe Domenico Scarlatti (Naples, 26 October 1685 Madrid, 23 July 1757) was an Italian composer who spent much of his life in the service of the Portuguese and Spanish royal families.
 He is classified primarily as a Baroque composer chronologically, although his music was influential in the development of the Classical style and he was one of the few Baroque composers to transition into the classical period.
 Like his renowned father Alessandro Scarlatti, he composed in a variety of musical forms, although today he is known mainly for his 555 keyboard sonatas.
Francesco Scarlatti (5 December 1666 – c. 1741) was an Italian Baroque composer and musician and the younger brother of the better known Alessandro Scarlatti.
Pietro Alessandro Gaspare Scarlatti (2 May 1660 – 22 October 1725) was an Italian Baroque composer, especially famous for his operas and chamber cantatas.
 He is considered the founder of the Neapolitan school of opera.
 He was the father of two other composers, Domenico Scarlatti and Pietro Filippo Scarlatti.
This is a list of the operas of the Italian composer Gioachino Rossini (1792–1868).

Naples has played an important and vibrant role over the centuries not just in the music of Italy, but in the general history of western European musical traditions.
 This influence extends from the early music conservatories in the 16th century through the music of Alessandro Scarlatti during the Baroque period and the comic operas of Pergolesi, Piccinni and, eventually, Rossini and Mozart.
 The vitality of Neapolitan popular music from the late 19th century has made such songs as "'O Sole mio" and "Funiculì Funiculà" a permanent part of our musical consciousness.
Griselda is an opera seria in three acts by the Italian composer Alessandro Scarlatti, the last of Scarlatti’s operas to survive completely today.
 The libretto is by Apostolo Zeno, with revisions by an anonymous author.
 Zeno wrote his work in 1701 and it had already been set by Pollarolo and Antonio Maria Bononcini (Albinoni, Giovanni Bononcini and Vivaldi would later produce versions).
 It is based on the story of Patient Griselda from Boccaccio's "Decameron".
 Scarlatti's opera was first performed at the Teatro Capranica, Rome in January, 1721 with an all-male cast (five castratos and a tenor).
