Here's one for the musicians out there...even Joe.
I was on another forum today, and they have a huge 20 plus page thread/battle going about this song.
The big fight is about what key is this song in...D or G? Apparently, Ed King said the solo came to him in a dream the night before recording it, and he played the whole thing thru in one take. Then the producer (Al Cooper-a schooled musician) wanted him to do it over again, because he said he played it in the wrong key (G instead of D). The rest of the band looked at him like he was crazy (I think this is one of the iconic solos in rock, almost a song unto itself). Apparently, it drove Al crazy and he even took the song to Mike Bloomfield to get his opinion.
So pretty much, all the theory guys say that the song is in D, and all of the feel, play by ear types (like Ed), say the song is in G.
My main question that came out of this thread is maybe not necessarily what key is the song...but...what does the song resolve to (that may be the same thing?)...G or D.
To me, my ear tells me the song resolves to G, (and I would play Gmaj pent to get that country type sound like Ed).
What are your thoughts?
PS. I've never played this song in any band I've been in, but if I had to play it, I think it would be fun to get it exact.
I'm a play by ear guy that has been self-studying theory for several years now...
I think you're correct on resolving to Gmaj. The overall progression is a reverse I IV V, where V = D, IV=C, and I = G. This ingeniously simple progression is repeated. The solo is played in G.
However, for those that insist on D mixo, which has the same notes as Gmaj, could opt for the less known I,vii7, IV progression, but I digress.
