If you’re a Jazz fan, Matias notation is tailor‑made for Jazz.
There’s no better proof of that than John Coltrane’s Giant Steps — especially since they’re BOTH based on the circle of fifths.
Read the first chapter of the book (available free) and you will KNOW the circle of fifths — it’s the first step to understanding Coltrane’s iconic Jazz masterpiece.
( and see if you can spot the overlapping fifths that define a major or minor7th chord )
