The first movement, marked 'Mit Lebhaftigkeit und durchaus mit Empfindung und Ausdruck' (with liveliness and with feeling and expression throughout), is in sonata form and features lyrical melodies and dynamic contrasts. The second movement, marked 'Nicht zu geschwind und sehr singbar vorgetragen' (not too fast and to be played very songfully), is a lyrical and introspective piece with a theme and variations structure. The sonata showcases Beethoven's mastery of emotional expression and innovative use of harmonic language.
