"The material of music is sound and silence; integrating these is composing. I have nothing to say and I am saying it." --John Cage
I always liked that last rather "Zen" line by John Cage. Funny they translated it into Japanese rather prosaically as 私は何も言わない。それが私の主張だから。(roughly, "I say nothing at all because that's what I advocate.") I guess if they translated it too directly people might just think it was a mistake.
I didn't turn the volume down as it suggests. I thought it was kind of cool to hear the stopwatch ticking, the shuffling of the paper, etc., and let that ambient noise blend with the noise around me.
