There is no theory. You have only to listen. Pleasure is the law. I love music passionately. And because l love it, I try to free it from barren traditions that stifle it. It is a free art gushing forth, an open-air art boundless as the elements, the wind, the sky, the sea. It must never be shut in and become an academic art.

And suddenly, without our wishing it at all, one of these memories spills from us and finds expression in musical language...I want to sing my interior landscape with the simple artlessness of a child.
