Question: Who was a prolific and influential composer of the Classical era; Pietro Mascagni or Wolfgang Amadeus Mozart?

full_context: Document 1: Franz Xaver Wolfgang Mozart: Franz Xaver Wolfgang Mozart (26 July 1791 – 29 July 1844), also known as Wolfgang Amadeus Mozart, Jr., was the youngest child of six born to Wolfgang Amadeus Mozart and his wife Constanze. He was the younger of his parents' two surviving children. He was a composer, pianist, conductor, and teacher from the late classical period whose musical style was of an early Romanticism, heavily influenced by his father's mature style.
Document 2: Mozart and scatology: Wolfgang Amadeus Mozart displayed scatological humour in his letters and a few recreational compositions. This material has long been a puzzle for Mozart scholarship. One view held by scholars deals with the scatology by seeking an understanding of the role of it in Mozart's family, his society and his times, while another view holds that such humour was the result of an "impressive list" of psychiatric conditions from which Mozart is claimed to have suffered.
Document 3: Ludwig van Beethoven: Ludwig van Beethoven ( , ; ] ; baptised 17 December 177026 March 1827) was a German composer and pianist. A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential of all composers. His best-known compositions include 9 symphonies, 5 piano concertos, 1 violin concerto, 32 piano sonatas, 16 string quartets, his great Mass the "Missa solemnis", and one opera, "Fidelio".
Document 4: Sì (operetta): Sì is an operetta in three acts composed by Pietro Mascagni to a libretto by Carlo Lombardo with verses by Arturo Franci. The libretto is based on Lombardo's operetta "La duchessa del Bal Tabarin" and Felix Dörmann's libretto for "Majestät Mimi" set by Bruno Granichstaedten in 1911. Mascagni's only venture into operetta, it premiered on 13 December 1919 at the Teatro Quirino in Rome. The operetta takes its name from its central character, Sì, an actress at the Folies Bergère, so called because she could never say no. ("Si" is the Italian word for "yes".)

Document 6: Mala Pasqua!: Mala Pasqua! (Bad Easter!) is an opera in three acts composed by Stanislao Gastaldon to a libretto by Giovanni Domenico Bartocci-Fontana. The libretto is based on Giovanni Verga's play, "Cavalleria rusticana" ("Rustic Chivalry") which Verga had adapted from his short story of the same name. "Mala Pasqua!" premiered on 9 April 1890 at the Teatro Costanzi in Rome, six weeks before Pietro Mascagni's opera "Cavalleria rusticana" which was also based on Verga's play. Bartocci-Fontana's libretto adds some elements that were not in Verga's original and expands on others. The name of the Santuzza character was also changed to Carmela, but the basic plot and setting remain the same. Its title refers to the curse which Carmela places on Turiddu, the lover who had spurned her: "Mala Pasqua a te!" ("May you have an evil Easter!"). Following its Rome premiere "Mala Pasqua!" had a few more performances in Perugia and Lisbon, but it was completely eclipsed by the phenomenal success of Mascagni's opera. After the 1891 Lisbon run it was not heard again until 2010 when it was given a semi-staged performance in Agrigento, Sicily.

Document 11: Pietro Mascagni: Pietro Antonio Stefano Mascagni (] ; 7 December 1863 – 2 August 1945) was an Italian composer most noted for his operas. His 1890 masterpiece "Cavalleria Rusticana" caused one of the greatest sensations in opera history and single-handedly ushered in the "Verismo" movement in Italian dramatic music. While it was often held that Mascagni, like Leoncavallo, was a "one-opera man" who could never repeat his first success, "L'amico Fritz" and "Iris" have remained in the repertoire in Europe (especially Italy) since their premieres. Mascagni said that at one point, "Iris" was performed in Italy more often than "Cavalleria" (cf. Stivender).
Document 12: Josef Mysliveček: Josef Mysliveček (9 March 1737 – 4 February 1781) was a Czech composer who contributed to the formation of late eighteenth-century classicism in music. Mysliveček provided his younger friend Wolfgang Amadeus Mozart with significant compositional models in the genres of symphony, Italian serious opera, and violin concerto; both Wolfgang and his father Leopold Mozart considered him an intimate friend from the time of their first meetings in Bologna in 1770 until he betrayed their trust over the promise of an operatic commission for Wolfgang to be arranged with the management of the Teatro San Carlo in Naples. He was close to the Mozart family, and there are frequent references to him in the Mozart correspondence.
Document 13: Cavalleria rusticana discography: This is a discography of Cavalleria rusticana, an opera by Pietro Mascagni. It premiered at the Teatro Costanzi in Rome on 17 May 17, 1890. There have been over 100 full-length recordings of "Cavalleria rusticana" published since it was first recorded in Germany in 1909. Mascagni himself has conducted the opera in two recordings, the best-known of which is the 1940 EMI recording made to mark the 50th anniversary of the opera's premiere. The performance by the La Scala orchestra and chorus with Lina Bruna Rasa as Santuzza and Beniamino Gigli as Turiddu also has a spoken introduction by Mascagni.

Document 15: Domenico Monleone: Domenico Monleone (January 4, 1875 – 15 January 1942) was an Italian composer of operas, most noted for his opera "Cavalleria rusticana" of 1907, which for a while rivalled the success of Mascagni's work of the same name which was from the same source. The work was the third opera to be based on Verga’s 1884 theatrical adaptation of his own short story, "Cavalleria rusticana", Stanislao Gastaldon’s "Mala Pasqua" (1888) being the first, and Mascagni's famous opera (1890) being the second.
