Watch the Affordable Shuffle online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Rhythm
This tune mixes a repeated riff and chords in-between, and here I'll show you three variations. In a real life playing situation, I'd have stayed on each groove longer. So, maybe two choruses on each variation in the blues.
You can also see how each of the three covers a different register on the guitar. This really adds to excitement and certainly interest. Notice how on this one my right hand is constantly moving, keeping the eighth note shuffle going. That's essential for this groove to sound right and groove properly. Think of your right hand as the drummer; it's keeping the time.
