I want to know the answer to the following question:
How many instrumental works did Chopin give a descriptive name to?
All the background I'm provided with is that "The Funeral March, the third movement of his Sonata No. 2 (Op. 35), the one case where he did give a title, was written before the rest of the sonata, but no specific event or death is known to have inspired it.". Is that enough to answer the question?
Answer: yes
