Masaya Yamaguchi

Masaya Yamaguchi (born July 18, 1970) is a guitarist and educator residing in Manhattan, New York City.

Career Yamaguchi grew up in Tokyo, Japan and decided to study in the U.S. at the age of 26. He became the first Japanese person to complete the master's program in Jazz Performance at City College of New York (M.A. 1999). He has written for Down Beat magazine and Annual Review of Jazz Studies, which is peer reviewed and published by the Institute of Jazz Studies at Rutgers University.

According to his profile in Marquis Who's Who in America, Yamaguchi has been a musician and educator who established his conceptual system to explore the imaginative formation of musical scales in The Complete Thesaurus of Musical Scales. His representative work, The Complete Thesaurus of Musical Scales was reviewed by John Kuzmich (senior columnist of Jazz Education Journal, International Association for Jazz Education) as "It's worth mentioning that this book comprehensively covers all theoretical possibilities in constructing scales...Take this Thesaurus Scales seriously, you will not be disappointed in the options available for jazz improvisation." "The Subsets of Limited Transposition" (which takes Olivier Messiaen's Modes of limited transposition and updates it) and "Appendix: Scales for Jazz Improvisation" in The Complete Thesaurus of Musical Scales are very helpful to organize musician's mind and ear. "The Subsets of Limited Transposition" was introduced in The Complete Thesaurus of Musical Scales, "Symmetrical Scales for Jazz Improvisation" and his academic article, "A Creative Approach to Multi-Tonic Changes: Beyond Coltrane's Harmonic Formula (Annual Review of Jazz Studies 12, 2002)." The concept of "The Subsets of Limited Transposition" has been updated by the "Lexicon of Geometric Patterns for Jazz Improvisation" as "Systematized The Subsets of Limited Transposition Families." Chapter VI of "Lexicon of Geometric Patterns for Jazz Improvisation" is also given to "Messiaen's Modes for Jazz Improvisation"

Masaya Yamaguchi is also known as a scholar and researcher of the music of Charlie Parker and John Coltrane. David Damsey is a co-author of John Coltrane Plays Coltrane Changes and a professor of music and coordinator of jazz studies at William Paterson University. In 2019, Yamaguchi published Miles Davis: New Research on Miles Davis & His Circle, featuring a foreword by Dave Liebman. The following year, the work was nominated for the Jazz Journalists Association (JJA) Jazz Award for "Book of the Year About Jazz."
