The third movement of this composer's second piano sonata in B-flat minor contains an often-performed funeral march. This composer popularized a musical form developed by John Field with his short piano nocturnes, and wrote an etude played only on black keys. This Romantic composer predominantly composed pieces for the piano such as the Heroic Polonaise, the Fantasie-Improptu in C sharp minor, and the Revolutionary Etude. For 10 points, name this nineteenth century Polish composer of the Minute Waltz.
