Sonata in C for clavier four-hands

Beginning in 1764, Mozart and his sister Maria Anna performed publicly together on the piano; they were likely the very first in Europe to play piano four hands in public, and Mozart also composed the earliest pieces for this setting. Further sonatas followed in Salzburg and Vienna. The Sonata in D major, K. 448 and the Fugue in C minor, K. 426 are Mozart’s only completed works for two pianos.
