Years ago for teaching purposes, I produced a short course on piano harmony, which I subsequently put online. After much revision and expansion, I’ve turned it into a slim e-volume with the title 20 Steps to Jazz Keyboard Harmony, published by Smashwords.
In 2020 I uploaded a revised, corrected, and improved edition, which is available here.
