His Piano Concerto No. 3 was originally intended to be a symphony but was published as a one-movement Allegro brillante posthumously. He wrote an un-numbered Manfred Symphony between his 4th and 5th, and his 7th was left unfinished at his death. The opening 36-bar Andante introduction is marked sempre marcatissimo in his Serenade for Strings, and his visit to Rome inspired his Capriccio italien. Using part of La Marseillaise in one piece  that often uses canons at the end, this is, for 10 points, what Russian composer of the 1812 Overture and Symphony No. 6, Pathetique?
