Been learning this in fingerstyle and trying to decipher what's happening with the chords. Here's what I've got so far. Any comments or able to help with the bit with question marks?
(As an aside, I'm so tired of just learning songs without understanding what's going on beneath in terms of chords and scales so I'm trying to analyse what I'm playing now - but I couldn't "think" this fast in real terms. Would love to see more deconstructions like this...).
D -> A7 -> F#m -- KEY OF Dmaj
D -> Am7 -> D7 -> G -- KEY OF G. First D is in Dmaj, moves to Am7 instead of A7 then II-V-I to G.
G -> D -> Em -> A7 -> D -- KEY OF D. Starts in G, though. II-V-I to D.. all those chords
appear in both D major and G major scales. Common Em - smart!
F#m -> G -> Bm -- KEY OF Dmaj (really F#m in this bit because it "sounds" that way)
Bm -> C -> D -> E -- KEY OF E at the end but not sure how it gets there ... ????
E -> B7 -- KEY OF Emaj.
E -> G#m -> A -- KEY OF Emaj (I III IV)
E -> Bm -> E7 -> A -- Emaj and II-V-I to Amaj (Bm is common - smart)
A -> E7 -> F#m -> B7 -> E -- Amaj then II-V-I to Emaj (F#m common - smart)
C#m -> E -> E7 -> A -- Still in Emaj then E7->A shifts to Amaj
A -> E -> F#m -> B7 -> E -- A maj then II-V-I to Emaj (F#m common)
