There's a way of playing safe, there's a way of using tricks and there's the way I like to play which is dangerously where you're going to take a chance on making mistakes in order to create something you haven't created before.
~ Dave Brubeck
Jazz stands for freedom. It's supposed to be the voice of freedom: Get out there and improvise, and take chances, and don't be a perfectionist - leave that to the classical musicians.
Many people don't understand how disciplined you have to be to play jazz... And that is really the idea of democracy - freedom within the Constitution or discipline. You don't just get out there and do anything you want.
Jazz is about freedom within discipline. Usually a dictatorship like in Russia and Germany will prevent jazz from being played because it just seemed to represent freedom, democracy and the United States.
