I have just read this autobiography and I found many interesting comments and anecdotes. Here’s one:
“I should like to quote a remark of Rimsky-Korsakov’s that he made later on when I became his pupil. I asked him whether I was right in always composing at the piano. “Some compose at the piano,” he replied, “and some without a piano. As for you, you will compose at the piano.” As a matter of fact, I do compose at the piano and I do not regret it.”
