The Piano Sonata No. 11 in A major, K. 331 (300i), by Wolfgang Amadeus Mozart is a piano sonata in three movements. It is uncertain where and when Mozart composed the sonata; however, Vienna or Salzburg around 1783 is currently thought to be most likely (Paris and dates as far back as 1778 have also been suggested). The sonata was published by Artaria in 1784, alongside Nos. 10 and 12 (K. 330 and K. 332).
Movement One – Mozart defied the convention of beginning a sonata with an allegro movement in sonata form. The theme consists of two 8 measure sections, each repeated, a structure shared by each variation. The tempo marking is “Andante Grazioso (Walking pace, gracefully)”. It is in the key of A major.
