Sometimes it works, sometimes it fails, but that's what we face when we're dealing with improvisation.

Jazz, for me, is a closed circuit, like the term baroque in the world of classical music.

Coltrane was moving out of jazz into something else. And certainly Miles Davis was doing the same thing.

Sometimes one succeeds, sometimes one fails.

When we talk about how improvisation works, we explain that it's like a pizza. Everyone gets to put a new topping on it, but it's all on the same crust.

Sometimes people have this notion that improvisation is simply intuitive leaping into the unknown.
