FTP, name this 35th symphony of Wolfgang Amadeus Mozart which was originally composed to honor the ennoblement of the namesake citizen of Salzburg.
One work named for this man was composed for the marriage of his daughter to Franz Xaver Spath, and is the longest of its composer's serenades.  A better-known work of this name begins with an allegro con spirito movement, and the composer noted that the  direction sciolto in its first movement called for "a clear and aggressive separation of the bowstrokes." Written in D major, it features a menuetto third movement followed by a lighthearted presto finale, which borrows from Osmin's comic aria "O how shall I triumph" from The Abduction from the Seraglio.
