So then what position would you call the one where the open fifth string would be an A and the open sixth an E with the d, g, b strings barred at the second fret for an A chord? I'm thinking if I'm playing out of a position that utilizes what would be described as a G chord in open position, the one you describe as A position, with the d, g, and b capoed, and the two E strings fretted three frets above the capo, that would be a G chord in open position, and therefore best described as G position, becoming A position if the nut or capo were dropped two more frets to allow the root and fifth to be played on te open fifth and sixth strings. Man, this is a lot easier to see than it is to describe!

Have to go look for the title of that BLJ song. The line I'm thinking of would be something like f, g, a, c, d, e flat. It sort of lands on an F minor 7th, but may actually start on a g note on sixth tring. Very distinctive sounding and cool, typical BLJ.
