Piano Concerto no. 3 / Piano Sonata no. 31

Piano Concerto No. 3 and Piano Sonata No. 31 are two works by Ludwig van Beethoven, composed in circa 1800–1803 and 1821 respectively. The concerto shows Beethoven's movement beyond Classical concerto conventions toward greater drama and virtuosic piano writing, while the sonata, from his late period, emphasises introspective lyricism and contrapuntal development, culminating in a fugue-inflected finale that reflects his late stylistic concerns.
