Improvisation is terribly haphazard.
There are some people, by the way, that associate a certain amount of visualization with the performance of music. Those are people that really are not centrally concerned only with music, the traditional things.
Hopefully, I have a certain amount of what you call musical talent.
We can use techniques in modifying things, in controlling things, but the first impulse has to be something that you simply cannot make just out of technique, or else it becomes perfectly evident that it is nothing but technique that you're exercising.
Besides merely some pleasure that we get out of the combinations of pitches together and lines, I think that there is some satisfaction that we get in the fact of having this diffuse thing organized very concretely and put onto a frame and have it actually decided.
A person improvising is sometimes very fortunate that just at that second things coincide.
