The String Quartet No. 14 in G major, K. 387, nicknamed the "Spring" quartet, was composed by Wolfgang Amadeus Mozart in 1782 while in Vienna. In the composer's inscription on the title page of the autograph score is stated: "li 31 di decembre 1782 in vienna". The work was perhaps edited in 1783. This is the first of the Haydn Quartets, a set of six string quartets he wrote during his first few years in Vienna in honor of the composer Joseph Haydn, who is generally viewed as the father of the string quartet form.
