Document 2: List of symphonies by Wolfgang Amadeus Mozart: This is a list of symphonies by the classical composer Wolfgang Amadeus Mozart. Symphonies No. 2 (attributed to Leopold Mozart) and 3 (written by Carl Friedrich Abel) are spurious. Spurious symphonies can be found at Mozart symphonies of spurious or doubtful authenticity. Symphonies that are suspected to be not Mozart's, but have not been proven to be the work of another composer, are in this list. Mozart's "37th symphony" is actually Michael Haydn's 25th symphony; Mozart only added a 20-bar slow introduction to it.

Document 9: Mozart, l'opéra rock: Mozart, l'opéra rock ("Mozart, the rock opera") is a French musical with music by Dove Attia, Jean-Pierre Pilot, Olivier Schultheis, William Rousseau, Nicolas Luciani, Rodrigue Janois and François Castello, lyrics by Vincent Baguian and Patrice Guirao and a book by Attia and François Chouquet. The show is a dramatization of the life of Wolfgang Amadeus Mozart beginning from the age of 17 and culminating with his death in 1791 at the age of 35. It uses both original pop-rock compositions as well as pre-existing music composed by Mozart.
Document 10: Leck mich im Arsch (Insane Clown Posse song): "Leck mich im Arsch" is a song by Insane Clown Posse and Jack White. The lyrics are inspired by Leck mich im Arsch, a scatological canon by Wolfgang Amadeus Mozart (K. 231/382c), while the music is based on a canon called Leck mir den Arsch fein recht schön sauber (K. 233/382d). The latter has for two centuries been attributed to Mozart but evidence has shown that the music of the piece was composed by Wenzel Trnka and Mozart merely replaced the original lyrics with his own.
Document 11: Mozart and G minor: G minor has been considered the key through which Wolfgang Amadeus Mozart best expressed sadness and tragedy, and many of his minor key works are in G minor. Though Mozart touched on various minor keys in his symphonies, G minor is the only minor key he used as a main key for his numbered symphonies. In the Classical period, symphonies in G minor almost always used four horns, two in G and two in B♭ alto. Another convention of G minor symphonies observed in Mozart's No. 25 and No. 40 was the choice of the subdominant of the relative key (B♭ major), E♭ major, for the slow movement; other non-Mozart examples of this practice include J.C. Bach Opus 6 No. 6 from 1769, Haydn's No. 39 (1768/69) and Johann Baptist Wanhal's G minor symphony sometime before 1771 (Bryan Gm1).

Document 13: 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 14: 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 15: 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.
