"The piece dies a natural death. It dies of old age."

"I find that as the piece gets longer, there has to be less material. That the piece itself, strangely enough, cannot take it. It has nothing to do with my patience. I don't know, my patience, how far it goes, you know. And I don't think about what your patience would be. I don't know that. In other words, I don't have a kind of psychological situation. Let's put it this way. I don't have an anxiety that I've got to stop. But there's less going into it, so I think the piece dies a natural death. It dies of old age."

Morton Feldman (Selected Interviews and Lectures, 1964-1987)
