Your Theory Book, excellent

Lee, not a question here, but I want to mention for everyone that I read your Guitar Theory book and was very impressed. My initial intention was to enhance my knowledge of Chord Progression and I certainly got that from your book. Too much to type here from all that I learned overall, but one thing is I never had anyone explain Modes so clearly. In your book you talk to the reader as though giving a private lesson, very level & human, and I respect that. I’m sure I’ll reference this book once in a while as needed. Thank you.
