Watch the Headed: Rhythm online guitar lesson by Gil Parris from NYC Rhythm & Blues
I'm going to break down the rhythm parts to Sister Sadie in the intro. Pay careful attention to the play between the major and minor 3rd. This adds to some of the bluesiness and I'm going to add some 4th voicings as well to create a vague "is it major or is it minor" kind of thing. The rhythm part in the beginning is kind of borrowed from Average White Band's "Cut the Cake". Check it out.
