Here is a PDF overview that explains how to play a major scale, minor scale, major chord, minor chord, what to do with your left hand, playing “passing notes”, and an introduction to chord progressions.
In this video I explain how to read and understand each chart. You definitely need to have watched the related videos in order to understand the charts, you should consider this a “refresher video”. This video is to help you review and remind you, not to teach you my number system if you haven’t watched any of the original videos first.
I hope you find it helpful!
