The Piano Sonata No. 12 in F major, K. 332 (300k) by Wolfgang Amadeus Mozart was published in 1784 along with the Piano Sonata No. 10 in C major, K. 330, and Piano Sonata No. 11, K. 331. Mozart wrote these sonatas either while visiting Munich in 1781, or during his first two years in Vienna. Some believe, however that Mozart wrote this and the other sonatas during a summer 1783 visit to Salzburg made for the purpose of introducing his wife, Constanze to his father, Leopold. All three sonatas were published in Vienna in 1784 as Mozart’s Op. 6.
