Just like Mozart, Chopin was a very gifted child and established himself as one of the foremost Polish composers at a very young age. One of the best piano composers and virtuoso pianists in history wrote almost exclusively for solo piano. But he also wrote two piano concertos and three sonatas. Chopin is also credited with the invention of the instrumental ballade and several musical innovations. Some of his best known works include Nocturne in E-flat major, Op. 9 No. 2, Funeral March (Prelude in C minor), Minute Waltz (Waltz in D-flat major), Revolutionary Etude (Op.10, No.12) and Fantasie-Impromptu (Op. Posth. 66).
