| Rachmaninoff’s Piano Concerto No. 2 Did you know that we may have hypnotherapy to thank for the existence of Rachmaninoff’s Piano Concerto No. 2? Rachmaninoff was in the midst of a four-year-long depression, caused by the near-universal excoriation of his first symphony and the death of his musical idol, Pyotr Ilyich Tchaikovsky. He found the treatment so helpful that he wrote Piano Concerto No. 2 in only a matter of months, and even dedicated it to the doctor who treated him.
