Captain: I did not say a G chord is just a G chord. Though I might well do. I said a G chord is just a chord. Which it is. Of itself, it is neither shit nor not-shit. Neither is it a bookcase or an orange. It is a chord. Which can, as you point out, exist in several different inversions. Which, as an accompanist, I have had plenty of time to think about, while the accordions and fiddles do their thing.
