Yes! When I figured this out I was also amazed why this is not theory lesson one with all teachers. It's such an essential skill and once you know it, it makes everything soooo much easierGreat lesson, and it was nice to put it up on YouTube and post it for everyone here to use. I wish someone had come along and taught this stuff to me that when I was learning to play by ear! I had to figure this out on my own, and I learned more with chords/arpeggios and chromatic approaches than songs. This would have been a lot faster!
