Hp,
I'm one of your students from Carmel, IN (USA), and I absolutely loved this lesson! You are 100% correct; it was not easy, especially at 40BPB. Good Lord, the uncomfortable silence made me think about what you said: timing, form (and the foot). Trust me, I can play G Blues; however, I never used the alternative chords of G13, C9, E9, D9, and A13. That opened my eyes. Now, here comes the best part. I was the designated rhythm player for two other guitarists when I arrived at a New Year's Eve jam last night. And it was my first time playing with these guys. The band opened with Atlanta Rhythm Section - Spooky. After the opening ADGB, the song goes back and forth between Em7 and A13. The chords were written (not displayed) on a teleprompter to follow. Here comes the best part: if I had not sunk my teeth into your "Slow Blues Guitar" lesson, I would not have recognized the A13 chord. Since I did - I NAILED the meatiest part of the song!! From that point, the night went great. Even better, I was invited back. For that, I say "thank you" HP.
Sincerely,
John Johantges
