When jazz is played in another nation, it is called American. When it is played in another country, it sounds false. Jazz is the result of the energy stored up in America.

Jazz I regard as an American folk music; not the only one, but a very powerful one which is probably in the blood and feeling of the American people more than any other style of folk music.

Not many composers have ideas. Far more of them know how to use strange instruments which do not require ideas.

An entire composition written in jazz could not live.

What the hell do you want to work for somebody else for? Work for yourself!

I didn't even start playing the piano until I was about 13 or 14. I guess I must have had a little talent or whatever-you-call-it, but I practised regularly, and that's what counts.

Jazz is one of the best things that you can find in your life, it can always be your friend.
