The Experience of Truth in Jazz Improvisation

In the jazz improvisative moment any inner-outer metaphors of spatiality become meaningless. Jazz improvisation is an activity, and activities relates to things in the world in a special way. The improvisations are not inside the instruments played just as the experience of improvisation is not inside the audience’s individual ears and minds. Jazz musicians say that they play the concert hall; they play the audience while being themselves played by the audience and the emerging musical improvisations.
How can we gain a deeper understanding of the wholeness and limitlessness of the jazz improvisative experience without limiting our search to those things that are rationally observable facts? Is it possible to ‘know’ more than we can rationally cogitate, and if so, could we find a way to unfold or explain this knowledge; that is, lay it out on a plain piece of paper such as the pages in this book?
