The material of music is sound and silence. Integrating these is composing.
Each moment presents what happens.
I have nothing to say, and I am saying it.
Theatre takes place all the time - wherever one is - and art simply facilitates persuading one this is the case.
The truth is that everything causes everything else. We do not speak therefore of one thing causing another. There are no secrets. It's just we thought they said dead when they said bread.
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.
