xx023x = xxDADx

I think by definition that is a power chord because of the root-fifth relationship between D and A.

For instance, x577xx has the same exact notes (same octave too) as xx023x, so wouldn't that mean that xx023x has to be a power chord too? Or are you going off the fact that xx023x doesn't have it's root on either the (low)E or A strings?
