This is an extraordinary piece for late intermediate pianists that explores a wide range of expressive musical ideas. Bonis masterfully uses a simple descending pentatonic scale as the theme, which is later on fragmented and developed. The main technique this piece will help you develop is crossing and alternating hands while playing melodies. Throughout the piece, both hands take turns in playing melodic notes, two notes at a time, while the left-hand reaches down to the bass notes and the right-hand fills in the harmony with broken chords.
