I was a painter, perhaps, but I am not any longer a painter. I didn't paint for many, many years - but at least two or three decades.

I never was very capable of expressing my feelings or emotions in words. I don't know whether this is the cause why I did it in music and also why I did it in painting. Or vice versa: That I had this way as an outlet. I could renounce expressing something in words.

Whether one calls oneself conservative or revolutionary, whether one composers in a conventional or progressive manner, whether one tries to imitate old styles or is destined to express new ideas - one must be convinced of the infallibility of one's own fantasy and one must believe in one's own inspiration.

I owe very, very much to Mozart; and if one studies, for instance, the way in which I write for string quartet, then one cannot deny that I have learned this directly from Mozart. And I am proud of it!

Great art presupposes the alert mind of the educated listener
