YAMAGUCHI Guitar Method
Masaya Yamaguchi is not only a musician but also a conceptualist who established his own system to explore the imaginative formation of musical scales by The Complete Thesaurus of Musical Scales, which is a meta-contribution to music pedagogy of a high standard. Jazz Education Journal wrote, "Its worth mentioning that this book comprehensively covers all theoretical possibilities in constructing scales July-August 2002." The concept is revealed in many of his writings and compositions. Because of the reference value of his outstanding achievements, Marquis Whos Who has selected his biographical profile for inclusion in Whos Who in America, Whos Who in the World and Who's Who of Emerging Leaders.
