Mozart: Piano Sonata in F Major, K. 533/K. 494Mozart: Piano Trio No. 2 in G Major, K. 496It could be said that all art is about communicating, but in music the idea of dialogue is particularly important, especially in the music of Mozart. One thinks right away of his great opera finales, with characters talking to each other, over each other and to themselves in a wonderful cacophony. But Mozart encapsulates this same essential dialogue in instrumental music, too, and even in solos. In the first movement of the piano sonata on today’s program, the allegro, Mozart uses a lot of counterpoint, and you can hear the exchange of ideas between high and low voices. In the piano trio, we hear the beginnings of the type of chamber music which would come to dominate, in which all players are equal partners in the music-making.
