The String Quartet No. 14 in G major, K. 387, nicknamed the "Spring" quartet, was composed by Wolfgang Amadeus Mozart in 1782 in Vienna. In the composer's inscription on the title page of the autograph score is stated: li 31 di decembre 1782 in vienna.[1] 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 and dedicated to Joseph Haydn.
