During the filming of Roman Polanski's 1992 film about Chopin (The Pianist) Adrian Brody lost 30 lbs. If  we try hard enough we could play an easy arrangement of this Waltz in A Minor and even lose a few pounds. Early and intermediate players need to play the base and treble clefs separately at the onset. Brody spent time away from the piano throughout the film in other scenes portraying this composer. Just saying.
