Philosopher Jacques Derrida Interviews Jazz Legend Ornette Coleman: Talk Improvisation, Language & Racism (1997)
[T]he idea is that two or three people can have a conversation with sounds, without trying to dominate or lead it. What I mean is that you have to be… intelligent, I suppose that’s the word. In improvised music I think the musicians are trying to reassemble an emotional or intellectual puzzle in which the instruments give the tone. It’s primarily the piano that has served at all times as the framework in music, but it’s no longer indispensable and, in fact, the commercial aspect of music is very uncertain. Commercial music is not necessarily more accessible, but it is limited.
