I Agree that Mozart's "a little night music" should be preserved since i played it many times when i was in my middle school and high school orchestra. There are also Many variations of Allegro, in different keys and arrangements done by other composers but all used mozarts fundamental theme. I had no idea though that it was lost for a while and then later found, and that it use to have 5 parts but the fifth being lost. Do you know if mozart created at other peices of art( like paintings or sketches) or did he strictly stay with creating music?
