String sextet

In classical music, a string sextet is a composition written for six string instruments, or a group of six musicians who perform such a composition. Most string sextets have been written for an ensemble consisting of two violins, two violas, and two cellos. Among the earliest works in this form are the six string sextets Op. 23 of Luigi Boccherini, written in 1776. Other notable string sextets include the Op. 18 and Op. 36 of Johannes Brahms, the Op. 48 of Antonín Dvořák, the Souvenir de Florence Op. 70 of Pyotr Ilyich Tchaikovsky, and the Verklärte Nacht Op. 4 of Arnold Schoenberg.
