String Quartet No. 14 (Mozart) String Quartet No. 14 (Mozart) 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.
String Quartet No. 4 (Babbitt) String Quartet No. 4 (Babbitt) String Quartet No. 4 is the fourth of six chamber-music works in the string quartet medium by the American composer Milton Babbitt. Babbitt’s Fourth Quartet was written in 1970, almost immediately after the Third Quartet. It is in a single movement, divided into twelve sections marked by (amongst other things) five different metronomic tempos, distributed 1-2-3-1-4-5-1-2-5-3-4-1. In contrast to its predecessor, the Fourth Quartet makes extensive use of coloristic instrumental effects, such as col legno, sul ponticello, and pizzicato glissando. Octave relations are especially important in this work. Contrasts of register, instrumental setting, timbre, duration
