Chicken Pickin': Rhythm 1 - Breakdown is a video guitar lesson presented by Joe Dalton and is sourced from Big Twang.
This rhythm part is similar to a standard root and fifth bass with chords on the second and fourth beats. Adding the flatted seventh as pick up notes sets the groove and feel for other soloists or singers.
This rhythm part may be quite busy for a recording session, but in a live situation, especially in a smaller band it can be quite effective.
