The material of music is sound and silence. Integrating these is composing.

For myself and my own experience now, I don't really need any music. I have enough to listen to with just the sounds of the environment. I listen to the sounds of 6th avenue.

It is not futile to do what we do. We wake up with energy and we do something. And we make, of course, failures and we make mistakes, but we sometimes get glimpses of what we might do next.

Discord occasions a momentary distress to the ear, which remains unsatisfied, and even uneasy, until it hears something better. I am convinced...that provided the ear be at length made amends, there are few dissonances too strong for it. Disharmony, to paraphrase Bergson's statement about disorder, is simply a harmony to which many are unaccustomed.

After I had been studying with him for two years, Schoenberg said, ‘In order to write music, you must have a feeling for harmony.’ I explained to him that I had no feeling for harmony. He then said that I would always encounter an obstacle, that it would be as though I came to a wall through which I could not pass. I said, ‘In that case I will devote my life to beating my head against that wall.’

All great art is a form of complaint

In an utter emptiness anything can take place.
