Claude Debussy said this quote

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.

~ Claude Debussy

Music is the silence between the notes.

~ Claude Debussy

Art is the most beautiful deception of all. And although people try to incorporate the everyday events of life in it, we must hope that it will remain a deception lest it become a utilitarian thing, sad as a factory.

~ Claude Debussy

There is nothing is more musical than a sunset. He who feels what he sees will find no more beautiful example of development in all that book which, alas, musicians read but too little - the book of Nature.

~ Claude Debussy
