Ein musikalischer Spaß in F major, KV 522 "Ein musikalischer Spass ; A Musical Joke ; Divertimento ; Bauernsinfonie ; Dorfmusikantensextett"

A Musical Joke (in German: Ein musikalischer Spaß) K. 522, (Divertimento for two horns and string quartet) is a composition by Wolfgang Amadeus Mozart; the composer entered it in his Verzeichnis aller meiner Werke (Catalogue of All My Works) on June 14, 1787. Commentators have opined that the piece's purpose is satirical – that "[its] harmonic and rhythmic gaffes serve to parody the work of incompetent composers" – though Mozart himself is not known to have revealed his actual intentions.
