Professor of the Moscow Conservatory and P. Tchaikovsky's friend, V. Fitzenhagen was the first to perform "Variations on a Rococo Theme" together with the orchestra under N. Rubinstein. The performance took place at the Symphonic Assembly of the Moscow department of the Russian Music Society on November 18, 1877.
Sextet "Souvenir de Florence" for two violins, two violas and two cellos in D minor, Op. 70, was composed by P. Tchaikovsky in June - August 1890 and was altered in January, 1892. It was dedicated to the Chamber Music Society in St. Petersburg. The Sextet was a great success. The composer reached an almost orchestral richness of sound due to the abundance of imitations and the simultaneous combination of different motives.
