Variations on a Theme of Chopin, op. 22 / Variations on a Theme of Corelli, op. 42

Variations on a Theme of Chopin, Op. 22 and Variations on a Theme of Corelli, Op. 42 are solo piano works by Sergei Rachmaninov, composed in 1902 and 1931 respectively. Both pieces employ the variation form within a late-Romantic harmonic and pianistic language, with Op. 22 exhibiting virtuosic, expansive textures and Op. 42 adopting a more austere, contrapuntal approach that reflects a mature phase in his compositional development.
