„No one can put a style on me. I've learned from many people. I change all the time. I experiment to keep up with what is going on, to hear what everybody else is doing. I even keep a little ahead of them, like a mirror that shows what will happen next” laŭ biografio de Mary Lou Williams ĉe All About Jazz
