Masaya Yamaguchi, musician, educator; July 18, 1970.                                        
Masaya Yamaguchi was born as a second son in Nagano at birth and bred in Tokyo, Japan. During the mid-80's, he started playing the guitar in rock/pop style (the ridiculous affair still comes to his mind now and then). Yamaguchi became interested in jazz through a TV commercial [of "Suntory White"] by Japan's renowned distiller, which misleadingly featured the jazz bassist, Ronald Carter.

Afterwards, Yamaguchi made his first purchase of a traditional 4-beat jazz album, which was John Coltrane's Giant Steps. At the age of 20, Yamaguchi changed his guitar style completely into jazz under the strong influence of John Coltrane--developing his own guitar style by all fourths tuning (E, A, D, G, C, F  from the bottom to the top) All Fourths: A Method For EADGCF Tuning On Guitar (Masaya Music, 2018). He also began to explore the imaginative formation of musical scales while majoring in English at Meikai University, Chiba, Japan (B.A. 1994). At the age of 26, he decided to study in the jazz program at the City College of New York where his idol, Ron Carter, directed; however, Yamaguchi was distressed about power harassment from some faculty members. During his college years, he performed with Chico O'Farrill's son, Arturo O'Farrill in the Graduate Jazz Ensemble. Whereas he was tormented by tendonitis, he professionally began to transcribe the recorded performances by John Coltrane, Charlie Parker and Miles Davis. In the end of 20th century, Yamaguchi became the first native Japanese who completed their Master program in jazz performance from the City College of New York (M.A. 1999).

Miles Davis: New Research on Miles Davis & His Circle (Foreword by Dave Liebman) is just released in June, 2019.

Masaya Yamaguchi is the author of the books John Coltrane Plays "Coltrane Changes" (Hal Leonard Corporation), The Bird Book - The Charlie Parker Real Book (Hal Leonard Corporation), The Complete Thesaurus of Musical Scales, Symmetrical Scales for Jazz Improvisation, Pentatonicism in Jazz: Creative Aspects and Practice (Masaya Music Services; formerly from Charles Colin Music Publications),  Lexicon of Geometric Patterns for Jazz Improvisation (Masaya Music Services), YAMAGUCHI Improvisation Method and Chromaticisim in Jazz: Applying Techniques and Concepts and he has contributed articles to professional journals including Down Beat magazine, etc. Because of the reference value of Yamaguchi's outstanding achievements, the editors of Marquis Who's Who have selected his biographical profile for inclusion in Who's Who in America, Who's Who in the World and Who's Who of Emerging Leaders. He lives in Manhattan, NYC.
