It's useless to play lullabies for those who cannot sleep.

Everything you do is music, and everywhere is the best seat.

Which is more musical, a truck passing by a factory or a truck passing by a music school? Are the people inside the school musical and the ones outside unmusical? What if the ones inside can't hear very well, would that change my question?

With just one musician, you can really do an unlimited number of things on the inside of the piano, if you have at your disposal an exploded keyboard.

Not one sound fears the silence that extinguishes it. And no silence exists that is not pregnant with sound.

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.

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.’
