In 1839,
Frederic Chopin wrote a piece that has hints of Schumann. It begins with a sweet, rocking 6/8, but turns dark at 2:00 with an anguished section. The calm section returns, but goes in an unexpected direction, then turns pitch black in a storm of notes as the middle section returns. The coda is based on the middle section, and it ends in a minor key version of the opening.
