Review—Prinzip Improvisation

To Duval, German jazz vibraphonist Christopher Dell approached writing Prinzip Improvisation ("The Improvisation Principle") as he approaches performing music, preferring improvisation to premeditated structure. The book is therefore an attempt to grapple with the problem of using language to describe jazz' fluid musical processes, and a nonlinear text which an active reader may choose to interpret in his or her own way.
