Souvenir de Florence, for string sextet or string orchestra in D major, op. 70

The String Sextet in D minor "Souvenir de Florence", Op. 70, is a string sextet scored for two violins, two violas, and two cellos composed in the summer of 1890 by Pyotr Ilyich Tchaikovsky. The work, in the traditional four-movement form, was titled "Souvenir de Florence" because the composer sketched one of the work's principal themes while visiting Florence, Italy, where he composed The Queen of Spades. Tchaikovsky dedicated the work to the St. Petersburg Chamber Music Society in response to his becoming an Honorary Member.
