Classical Fact
When Tchaikovsky wrote his first piano concerto, he played it for his composition teacher, Nikolay Rubinstein, who, with heated discourse, declared it "worthless, absolutely unplayable, so unskillfully written that it couldn't even be improved." But Rubinstein offered to play it in concert if Tchaikovsky would re-write it. Tchaikovsky replied, "I shall not alter a single note."
