Watch the Shake A Little online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Rhythm
This etude is based upon Little Walter's "Shake Dancer". When I first hear this tune, it kinda blew my mind it was so cool. The amount of cool info in the original and the number of variations on the rhythm part make it a fantastic study in what can be done on a blues.
I've simplified the parts a little to get you going, but please listen to the original very closely and learn it. It's one of those tunes I love exposing people to as it's one of the best performances I can think of. It's also a great tune, so that helps!
