“Jazz Theory: Contemporary Improvisation, Transcription, and Composition offers a vast amount of prac-tical and speculative content which serves to guide, challenge, and inspire individuals in their pur-suit of musical understanding and creative excellence. Ron Westray has produced a compendium of useful and exotic resources which will serve as a beneficial aid for students, amateurs, scholars, and seasoned musicians. Performers, composers, theorists, and academics, working in or across a wide variety of contemporary ‘styles’ (e.g., jazz, rock, pop, country, latin, funk, gospel, urban), will find something useful and thought provoking in this impressive volume.”— Michael Coghlan, Associate Professor of Music, York University, Toronto, Canada

“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
