Watch the 4th Chords online guitar lesson by Jennifer Batten from Rock Sauce for Rhythm Guitar

There are a few elements I want to share within this groove. First of all, aside from the power chord 5ths, the rest of the groove is either 4th intervals or clusters of 4ths. The root is D (dorian). I could use this same shape and climb from the 2nd position all the way up the neck as long as all of the notes are in the key of C.
