Watch the Funk E online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Rhythm
In my introduction to this etude, I said repetition is funky. And as you listen through and work through the performance, you can see that I'm repeating the same phrase the first time through. The second time through I'm adding in just a slight variation to add a little more excitement and to change it up.
Overall, it's pretty much the same thing and this is what we hear when we listen to classic funk records like James Brown. It's an easy lesson to forget, because it seems as guitar players, we really want to play the guitar! It requires a lot of discipline and self-awareness stay in the groove and lay it down. Along with this exercise, I highly suggest picking up James Brown's greatest hits and learn every song on it.
