Piano Sonata No. 2 / 24 Préludes

Piano Sonata No. 2 and the 24 Préludes are compositions by Fryderyk Chopin, first published in 1839. The sonata is characterised by dramatic contrasts, dense textures and an unorthodox structural approach, while the 24 Preludes comprise concise pieces in all major and minor keys that display a wide range of moods, harmonic inventiveness and pianistic detail, marking a mature phase in Chopin's output and influencing later Romantic piano literature.
