The opening flurry is consists of riffs on wierd suspensions of the chords
Bm, A, G and F#, I think.
After that, it kicks into the main riff:
(Eb) |-----------------|-----------------|-----------------|-----------------|
(Bb) |-----------------|-----------------|-----------------|-----------------|
(Gb) |-----------------|-----------------|-----------------|-----------------|
(Db) |-----------------|-----------------|-----------------|-----------------|
(Ab) |-5-3-5-----------|---------------3-|-5-3-5-----------|-----------------|
(Eb) |-----------1---3-|-----------4-5---|-----------------|---2---3---4---5-|
1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 &
The verses continue with that chord progression -- D, then G. I think the
chorus was mostly F#m and E.
PLAY TOO ..
