Watch the Stop Here online guitar lesson by TrueFire from Play Acoustic Guitar 6: Lick Lexicon
Stop Here - Lick #19 is a video guitar lesson presented by Joe Dalton and is sourced from 50 Acoustic Blues Licks You MUST Know.
Here's another bonus set of licks. Some variations to lick 18 are listed here. In each of these examples, you will see that the melody note has changed. The corresponding four chord is also listed. You can mix and match any of these or combine them. I thought it would be a good idea to model some of the variations so you could get the idea of how I create them.
