Watch the G Slow Blues: 1st Chorus online guitar lesson by Robben Ford from Riff Revolution

With this first four bars, we're starting off slowly, something that people who know my playing know that I'm in the habit of doing (especially with something like the slow blues), and allowing a lot of space for things to develop. Everything that you play is going to be a note out of the scale of the chord you're playing in. It's sort of like you spell the chord: You're telling people what key you're in, or if you're major or minor.
