I know two kinds of audiences only--one coughing, and one not coughing.

Practice in tranquility.

Children are given Mozart because of the small quantity of the notes; grown-ups avoid Mozart because of the great quality of the notes.

The sonatas of Mozart are unique; they are too easy for children, and too difficult for artists.

The notes I handle no better than many pianists. But the pauses between the notes - ah, that is where the art resides.

Have I a secret about playing the piano? It's a very simple one. I sit down on the piano stool and make myself comfortable - and I always make sure that the lid over the keyboard is open before I start to play.

I practice in my head.
