Question: Under which government did this Italian classical composer, conductor, and teacher that became a source of inspiration for "A Little Nightmare Music" pursue his career?

full_context: Document 1: La passione di Gesù Cristo (Salieri): La passione di Gesù Cristo is an oratorio by composer Antonio Salieri that uses a libretto by Metastasio. While many composer's set music to this libretto, Metastasio is recorded to have said before Joseph II, Holy Roman Emperor that Salieri's setting "was the most expressive of any written on this poem." The work premiered in Vienna, Austria during the advent season of 1776.
Document 2: Domenico Foroni: Domenico Foroni (10 July 1796 - 24 March 1853) was an Italian composer, conductor, and music educator. He was born in Valeggio sul Mincio into a family of landowners. On 7 November 1818 he married Teresa Zovetto with whom he had five children, two of whom became famous: the operatic soprano Antonietta Foroni-Conti (1822-187?) and the composer and conductor Jacopo Foroni (1825–1858). In 1818 he was appointed to the dual position of director and principal conductor of the Teatro Filarmonico in Verona, a position he held for over 25 years. He was also highly active as a teacher of singing and music composition in that city. Among his notable pupils were Gottardo Aldighieri, Paolo Bombardi, Domenico Conti, Carlo Pedrotti, Alessandro Sala, Maria Spezia-Aldighieri, and his children. Most of his compositional output was sacred music, the majority of which was written for services at the Verona Cathedral. Most of his music is now lost, but copies of his "Miserere" and "Messe" still exist
Document 3: Per la ricuperata salute di Ofelia: Per la ricuperata salute di Ofelia (For the recovered health of Ophelia), K. 477a, is a solo cantata for soprano and fortepiano composed in 1785 by Antonio Salieri and Wolfgang Amadeus Mozart, formerly thought to have been enemies, and a third, unknown composer, Cornetti, to a libretto written by the Vienna court poet Lorenzo Da Ponte. It is speculated that "Cornetti" may refer to Alessandro Cornetti, a vocal teacher and composer active in Vienna at the time, or that it is a pseudonym of either Salieri or Stephen Storace, a composer who organized the collaborative work to honor his famous sister. The music had been considered lost until November 2015, when German musicologist and composer Timo Jouko Herrmann identified the score while searching for music by one of Salieri's ostensible pupils, Antonio Casimir Cartellieri, in the archives of the Czech Museum of Music in Prague.

Document 7: A Little Nightmare Music: A Little Nightmare Music is an opera in "one irrevocable act" by Peter Schickele under the pseudonym he uses for parodies and comical works P. D. Q. Bach. The title of the work refers to the English translation of Mozart's famous "Eine kleine Nachtmusik" ("A Little Night Music"). The opera is described as being "based on a dream he had December 4, 1791, the night that Wolfgang Amadeus Mozart died and Antonio Salieri didn't." The opera was "newly exhumed" (a.k.a. premiered) at Carnegie Hall on December 27, 1982. It was later recorded with the premiere cast and released on CD by Vanguard Records in 1983.

Document 9: Mozart 252: Mozart 252 is a 2008 album by Michael Nyman (his 58th release) with the Michael Nyman Band, Hilary Summers, and Andrew Slater, celebrating the 250th anniversary of Wolfgang Amadeus Mozart's birth. Although "Revisiting the Don," one of only two newly written works on the album, was commissioned and performed in 2006, the album's title is a joke on its lateness as an album, released 252 years after Mozart's birth ("it seemed more appropriate to miss the beat by two years"). The album also includes "In Re Don Giovanni," Nyman's first composition for the band, which is based on the first fifteen bars of "Madamina, il catalogo è questo" from "Don Giovanni", six selections from Peter Greenaway's film, "Drowning by Numbers", in which he was instructed to base the music on the slow movement of Mozart's Sinfonia Concertante K. 364, and two duets and an aria from Nyman's television opera, "Letters, Riddles and Writs", in this recording featuring bass Andrew Slater as Leopold Mozart and contralto Hilary Summers as Wolfgang.
Document 10: P. D. Q. Bach: P.D.Q.Bach is a fictitious composer invented by musical satirist "Professor" Peter Schickele. Schickele developed a five-decade-long career, performing the "discovered" works of the "only forgotten son" of the Bach family. Schickele's music combines parodies of musicological scholarship, the conventions of Baroque and classical music, and slapstick. The name "P.D.Q." is a parody of the three-part names given to some members of the Bach family that are commonly reduced to initials, such as C.P.E., for Carl Philipp Emanuel Bach. "PDQ" is an initialism for "pretty damned quick".

Document 13: The Magic Flute: The Magic Flute (German: Die Zauberflöte ), K. 620, is an opera in two acts by Wolfgang Amadeus Mozart to a German libretto by Emanuel Schikaneder.
