Read this: Chopin's public popularity as a virtuoso began to wane, as did the number of his pupils, and this, together with the political strife and instability of the time, caused him to struggle financially. In February 1848, with the cellist Auguste Franchomme, he gave his last Paris concert, which included three movements of the Cello Sonata Op. 65.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What instrument did Auguste Franchomme play?
Cello
