Watch the Power Chords online guitar lesson by Denny Sarokin from Songwriter's Guide to Great Guitar

Power Chords are 3 note bass driven chords using only the root, 5th, and octave notes. It has no 3rd or flatted 3rd, so they can be used for substitution for both major and minor progressions. They’re great for creating chord pads or creating memorable riffs and intros (“Smoke On The Water”, “Cinnamon Girl”, Jessie’s Girl”).
