Ashby has helped many musicians with his unique ability to transfer his skillset to others. After many years of experimentation, Ashby developed his theory of Nine Tone Scales and published his notes as the "Diminished Augmented System of Harmony and Scales". Ashby is the first and only musician to outline the symmetric harmonic construction and systematic relationship of nine tone scales for practical use in the 12 tone system. His understanding and detailed analysis of the NINE TONE Harmonic Matrix has opened the minds of musicians around the world to a system of harmony that is not taught in any college or university.
"I've followed Ashby's lead and have been writing stuff based on this scale system -your work exploring the systemic implications of is a definite advancement, no question. "
- Jon Burr
Bassist and Composer from NYC
" My interests is to understand your system and how I can apply it- especially in writing harmony"
