Wolfgang Amadeus Mozart A Musical Joke, KV. 522, set of parts - Urtext Edition - 2 violins, viola, basso continuo and 2 horns in F. editor: Loy, Felix. This Henle edition is full of mistakes! The publisher can freely admit this, because the odd notes here all come from Mozart himself – he consciously inserted them into his Musical Joke. In this amusing and mischievous piece, Mozart does not chiefly parody musicians who play wrong notes (the later title “Village Musicians” was not his).
