Chopin developed many new forms of piano music, from the kind of audacious miniatures found among the mazurkas to extended single-movement works such as the ballades and scherzos. But he also wrote three piano sonatas, drawing on structures inherited from Mozart and Beethoven. The Piano Sonata No.3, Op. 58, was completed in 1844 and its first movement is in sonata form. Even so, the music seems closer to the world of Chopin’s ballades than to any classical models, particularly in the rhapsodic development section. The outer sections of the Scherzo are filled with rapid movement, the ideas delicate and airy, while the slow Trio is richly harmonised but never loses its hints of unease. After a declamatory opening, the slow movement – a Chopin nocturne in all but name – is dominated by the song-like melody heard near the start, the mood changing for a dream-like central section before returning to the opening idea. The finale has a seemingly unstoppable momentum and energy, and for Marceli Antoni Szulc, Chopin’s first Polish biographer, this movement evoked images of the Cossack Mazeppa on a galloping horse.
