Now you know basic and inverted power chords on the E and A strings. BUT if you want to put a power chord on any other string, you must know this key bit of information: ANY NOTE ON THE B STRING MUST BE "PUSHED" OVER ONE FRET HIGHER TO MAINTAIN ITS NORMAL SOUND. This is because the B string does not follow the pattern that the 5th fret on the string below another string is that note. For example:
The fifth fret on the E string, is the same note as an Open A.
However, The B string is the 4th fret on the G string, so therefore you must alter your fingering for these higher power chords.
These are some charts of power chords above the A string.
