Hey everyone!
I know there are many fix you tabs/chords out there, but all of them seem to miss a subtle but beautiful bass movement in the bridge section of song.
So this is how the chords are played by coldplay themself:
Intro & Couplet:
Eb - Eb/F - Eb/G - Bb/D - Eb/C - Eb/Bb
This chord progression is just repeated over the intro and all couplets except for the last one.
Chorus:
Ab - Bb - Ab - Bb - Ab - Bb
The bridge uses the following chords
Eb - Absus2 - Eb - Bbsus4 - Bb
This is repeated many times, but the last two times are a little bit diffent. They have a intresting bass line wich is played as followed:
Eb - Absus2 - Eb - Bbsus4/D - Bb/D
Cm - Absus2 - Eb - Bbsus4 - Bb
Listen to how I play it here in my cover of the song, at 4:06 :
And here at 3:52 :
Hope I helped you :)
