“Ron Westray’s solos make music that, however complex, fits perfectly at the moment of its crea-tion into an ensemble performance. That music seems to materialize like magic. In this book, We-stray demystifies the magic by explaining it in thorough and precise terms as a systematic method—‘like math,’ as he says. That method can be learned in concept and practice by those willing to work hard enough. That, according to him, can make great improvisation accessible to most anyone.”— Gregory Clark, Emeritus Professor of English, Brigham Young University, Provo, UT
