Piano Concerto No. 10 (Mozart)
It is not known when Mozart completed this concerto for two pianos, K. 365/316a, but research by Alan Tyson shows that cadenzas for the first and third movements are written in his and his father's handwriting on a type of paper used between August 1775 and January 1777. It is presumed that Mozart wrote it to play with his sister Maria Anna (“Nannerl”). Years later he performed it in a private concert with pupil Josepha Barbara von Auernhammer.
The concerto departs from the usual solo piano concerto with the dialogue between the two pianos as they exchange musical ideas. Mozart divides up the more striking passages quite evenly between the two pianos. Also, the orchestra is rather more quiet than in Mozart's other piano concertos, leaving much of the music to the soloists.
The first movement is lyrical and "wonderfully spacious, as if Mozart is thoroughly enjoying himself and letting his ideas flow freely," as Ledbetter has noted. The middle movement is slow and refined; the orchestra stays in the background behind the pair of playful pianists. The finale is a rondo filled with rhythmic drive and, after passages of lyrical grace, there is an exuberant return to the main rondo theme.
