Watch the Funk-O-Rama - Rhythm online guitar lesson by Jeff Scheetz from Rock Solid

So when we have a funky rhythm with a lot of right hand motion, we kind of have to focus on what the left hand is doing and how to vary it to stay in the groove of the right hand. Little hammer-ons and slides usually do the trick.
Remember, once you get used to keeping that right hand going in a steady motion, that really opens you up to be able to do lots of things with your left hand. A steady right hand rhythm is a forgiving thing for your left hand!
