Description
The song is essentially a 12 bar blues in G minor. The progression is as follows:
|| Gm7 | Gm7 | Gm7 | Gm7 | Cm7 | Cm6 | Gm7 | Gm7 | Eb | D7sus | Gm7 | Gm7||
You may notice the use of a 6 to 5 turnaround here instead of the classic 5 to 4. This is pretty common in a minor blues!
The G minor, or the 1 chord, is treated with the signature rhythm from the intro. The C minor is played as a minor 7 on the 8th fret for the first measure then a C minor 6 chord on the second measure. The rhythm here matches the triple feel with added muting in between and a double stroke at the end. Return to the 1 chord for two measures.
The Eb and D chords are played with a much straighter rhythm: 1 2 3&4. However, when you play the D7 chord, suspend it for two beats then un-suspend it and return to G minor 7 for the last two measures.
The acoustic guitar plays it's original counterpoint over the Gm7 and then during the Cm7 and Cm6 it plays a half step melody between Eb & D still on the triple rhythm. During the turnaround it doubles the electric guitar on Eb and D7sus.
