"There are two things about Schnabel. I think he was certainly one of the most important influences of the twentieth century, pretty much on all music. But what was most striking was the level of inspiration every time his fingers touched the keyboard. It was a highly moving, almost kind of life-transformative experience. And one of the reasons was there was little caprice in his approach to music. ‘Because I feel it that way’ was never a sufficient reason to do something; that is arbitrary and it had no place in his lessons either. Everything that he did, he could point to the text, and the text - an urtext, an original text - was terribly important to him. His edition of the Beethoven sonatas is so instructive because his ideas and suggestions are in a different print than what Beethoven wrote; you can always distinguish between Beethoven and Schnabel. But that kind of dedication, that kind of musical integrity to the desires and instructions from the composer, gave it an authenticity that was irresistible, and that was combined with his level of inspiration. Very quickly, it became impossible to distinguish between Mozart and Schnabel, Beethoven and Schnabel, or Schubert and Schnabel; he became the musical personification of the composer, which is why it was so irresistible what he did."
