Перевод текста
everyone has heard of rachmaninoff. he was a famous pianist. He was also a famous composer. Rachmaninoff liked to tell this story about himself. When I was a very small boy, I once played the piano at a party in the house of a Russian nobleman. I was only eight years old. But i had been playing the piano for several years. I played well. I played the "Kreutzer Sonata" has in it several very long rests. In each of these rests I took my hands from the piano and waited. To me this was very dramatic. I had been playing for some time and I had already made some dramatic rests when an old lady came up to me. She said: 'My boy, why don't you play us something that you know?'"
