Our music this week is the “Kegelstatt” trio by Wolfgang Amadeus Mozart. It features three instruments that are not commonly associated with one another: piano, clarinet, and viola.
Mozart apparently loved to play “skittles,” which is his era’s name for what we now call bowling. The contestants threw or rolled a wooden ball or disk in an attempt to knock down a row of nine pins. The manuscript for the Trio contains the inscription: “Wien den 27.t Julius 1786 untern Kegelscheiben” (which translates as “Vienna, 27th July 1786 while playing skittles”). “Kegelstatt” literally means “The Skittles Trio.”
Like most trios of Mozart’s time period, this trio has three movements. The first is Andante (a gently flowing tempo) that begins with an iconic five-note ornamental figure. Listen for the repetition of that five-note figure throughout the entire sonata. The second movement is a Menuet that is predominantly a conversation between the clarinet and the viola. Mozart experiments with chromaticism here (the playing of successive half-steps to create an erie, unsettling atmosphere). The third movement, Rondo, is structured with a returning theme: A-B-A-C-A-D-A. Between the B, C, and D developments, the A theme returns. Listen for the fascinating ways in which Mozart recycles the A theme with a different flourish each time.
