Wolfgang Amadeus Mozart's Piano Sonata in F major, K. 547a (Anh. 135) is a sonata in two movements. It was originally published as an original sonata by Breitkopf and Härtel in 1799 but was soon found to be an amalgam of movements culled from other compositions. It is sometimes called Mozart's Piano Sonata No. 19.
Movements The work has two movements:
The set of six keyboard variations on an original Andante, KV 54/547b/Anh.138a are sometimes played as an additional third movement to this piece. These variations are themselves also transcribed from the same violin sonata (K. 547) as the Allegro with its fourth variation (which was violin-centric in the original) re-written.Zaslaw, Neal, with Cowdery, William eds., The Compleat Mozart: A Guide to the Musical Works of Wolfgang Amadeus Mozart, p. 320, New York: W.W.
