I want to know the answer to the following question:
What instrument did Chopin play at  Adolphe Nourrit's funeral?
All the background I'm provided with is that "On 26 July 1840 Chopin and Sand were present at the dress rehearsal of Berlioz's Grande symphonie funèbre et triomphale, composed to commemorate the tenth anniversary of the July Revolution.". Is that enough to answer the question?
