Watch the G Slow Blues: 1st Chorus online guitar lesson by Robben Ford from Riff Revolution
In the second four bars of this chorus, I'm using pretty much the same theme that I established in the first four bars, taking it a little further.
This is a beautiful thing in blues, because blues is very conversational. When you play blues, you should be talking to people with your notes. And you don't want to blast them with notes right away, nobody wants to hear that! Or at times, maybe so, but in this case I have to develop five choruses, so I start low and slow and start moving it up.
