Watch the First Position Power online guitar lesson by Brad Carlton from Chord Studies: Power Chords Vol. 1
In this progression you are playing four different power chords, but staying down in first position. You start with an F5 , and then move your third finger over one string nod lift up your other fingers to get the G5 chord. Using the same shape as the F5, but now moving to a fifth string root we get the B♭5. Remember when you're getting the C5 to mute the fourth string!
