Sonata for Piano with 4 Hands in C major, K. 521: III. Allegretto
Classical Sonata Piano solo beta difficulty
In brief

The III. Allegretto has a playful, light character: short motifs answer between the two keyboards, with discreet accents and a dance-like motion that demands clarity of voices while remaining agile. You will face specific challenges in Harmonic Analysis (3.6/5): you must follow rapid chord progressions to anticipate inversions and adjust hand balance to bring out basses and inner voices; and in Phrasing (2.5/5): shaping the short phrases requires precise touch and careful legato so each response stays clear without losing momentum. The piece belongs to the Classical period and sits within the composer's chamber repertoire for piano four hands, showing his use of sonata procedure in an intimate, dialoguing format.
