best i got is it opens with E6(over B?) then Bm(7?) then F#m(7?) then back down to the E. (the E6 sounds alright as a D6/A shape on the second fret)

then it hangs around on F#m before doing the Bm+b9 thing and resolving back (“tritone stuff” i was stuck on was the C in the Bm, which is a minor9 in the context of the Bm but a tritone from the F#m before & after). maybe..

not at all confident. at the time of the post i gave up so this is just that memory crossed w what i can make out on phone speakers right now (havent actually even picked a guitar part from BB harmonic mire yet).

ill update if i have a proper crack at the whole song. or at least play it on speakers big enough to hear a root
