Music has a lot in com­mon with math­e­mat­ics. But in music, two and two need not make four: they add up to what­ever you wish.

I have discovered three things which know no geographical borders - classical music, American jazz, and applause as the sign of the public's favor.

There is no such thing as perfection, there are only standards. And after you have set a standard you learn that it was not high enough. You want to surpass it.

The discipline of practice every day is essential. When I skip a day, I notice a difference in my playing. After two days, the critics notice, and after three days, so does the audience.

Practice like it means everything in the world to you. Perform like you don't give a damn.

If I don't practice one day, I know it; two days, the critics know it; three days, the public knows it.
