I've been listening to the tune most of the day now. I'll have no problem buying that it's in B minor, but still I hear the E chord as home. The home chord is the IV of B minor. warmingtone seems to think quite a bit like I did, while strat a various has a radically different approach. I don't know if one is right and one is wrong, or if this is a case of one person describing gray as "kind of white" while another person says "kind of black". This is something I don't understand. Could you please elaborate? The way I understand it, the notes in the E mixolydian scale, set or collection are E, F#, G#, A, B, C# and D. From those you can build Bm, A and E(7). I think most, if not all, the notes James plays are within that collection. Or do you mean that the mixolydian sound just fits over the E7. Well, I'll buy that. Or is it something else that I'm just too ignorant to get? While I could see why E blues wouldn't work I could, with my poor imagination, just not see this tune as a vehicle for blues. I just sat down and played a little. Stylistically B blues fits way better than I could ever think. Interesting!
