If you mean do I use the guitar when I'm sitting at home writing stuff, then basically no, never. All I would ever write would be stuff that my fingers easily fall into.

You could say that everything the musicians have learned and known over the years, all of their technical resources, are in a dialogue with the things they are discovering every time, as if it was the first time.

There's an awful lot of resources that can be drawn upon in an improvised music concert.

I write with a mouse, because it has no psychological associations or memories or habits associated with it.

The totality of a record is usually beyond ones ability to imagine when you start working on it, but the component parts are, usually, fairly clear one way or another.

I started getting interested in the notes that I could hear being generated when I hammered on while playing a classical guitar.

Improvised music involves a lot of intuition and I like developing intuition.
