The Cello Sonata in G minor, Op. 65, was written by Fřďric Chopin in 1846. It is one of only nine works of Chopin published during his lifetime that were written for instruments other than piano (although the piano still appears in every work he wrote). Chopin composed four sonatas, the others being piano sonatas. The cello sonata was the last of Chopin's works to be published in his lifetime. The sonata was written for and dedicated to Auguste Franchomme. The sonata is remarkable for the concentration of its material: much of the music of the first movement grows out of the cellos opening statement, and certain theme-shapes appear in all its movements. The last three movements were first publicly performed by Franchomme and Chopin at the composer's last public concert, at the Salle Pleyel on 16 February 1848. - Wikipedia.
