Watch the G Slow Blues: 2nd Chorus online guitar lesson by Robben Ford from Riff Revolution
So in the second chorus, I've moved up the register a little bit. That first chorus I played it pretty much down low, and now I'm stepping up into a slightly higher register. Obviously, I'm playing something, I'm saying it again, and then I'm saying it again, and resolving it. So, it's played once, played twice for emphasis, and then driven home and resolved by moving down.
