Watch the Power Shift online guitar lesson by Brad Carlton from Chord Studies: Power Chords Vol. 1
In this progression we are playing power chords that have four voices: root, fifth, root, fifth. The first chord is C5, which is not too hard to play but watch your intonation. Shift down a whole step to get the B♭5. Then we are going shift over to a fifth string root which gives us another fingering for the same voicing. Shift that up a whole step and grab the F5.
