Watch the Shuffle Groove: 1 online guitar lesson by Andy Aledort from Progressive Blues Power

Here's a shuffle rhythm part in the key of D, build from a slight twist on the standard 12-bar blues, that combines the use of open strings with thumbed-root chord voicings (with added riffs) for the IV7, G7, the bVI, Bb7, and V7, A7 chords. Notice also the cool A7#9 Jimi Hendrix-type voicing that wraps up the progression each time.
