Watch the Permutations online guitar lesson by Jennifer Batten from Rock Sauce for Rhythm Guitar
This is the comping underneath the solo section in my tune "Headbanger's Hairspray" from my "Above, Below, and Beyond" CD. The harmony is a simple I, IV, V progression in E (dominant) (E7, A7, B7). The first phrase is a permutation of a basic blues boogie woogie pattern. I leave a lot of space with the IV chord (bars 5 and 6) to let things breathe as well as the V to IV chords in bars 9 and 10. There is tension built in the final bar (12) using a chromatic climb.
