Alexis Weissenberg on musical virtuosity

"First of all, one must definitely draw a line between what is really indeed difficult and what isn’t. We all know that what is most difficult is to play a Mozart adagio perfectly well. Technically! I wish more people would understand this; when most people speak of technique, they still speak of the Liszt rhapsodies, as opposed to anything else. A Beethoven adagio, a Schubert sonata (the slow movement) are the most difficult thing to achieve on the keyboard. It reaches such dimensions of nervous control, and of sound control, and if really anybody can achieve this from A to Z, then we can say that this person is not only a great musician, but a great technician.”
