Tuning: DADGAd (sort of an open Dsus4) First off, I found it pretty challenging to figure out what tuning Mark uses on this song, but after watching some live footage I'm pretty sure this is the correct tuning, except he uses a baritone guitar, tuned one forth lower. (So, if you are lucky enough to own a baritone guitar, the tuning would be: AEADEa) For the rest of us, tune the guitar to DADGAd (put a capo on the 7th fret if you want to play along.) The chord progression is, as I interpret it (somewhat vague): D - G/D - Bm7/D - F#m/D - G - Gmaj7/F# - Dsus4/E - Dsus4/E Listen to the song for the timing and pattern, this is just how I play it: d|---------------------------------------------------| A|---------------------------------------------------| G|--11-------11--9---------9--7--------7--6--------6-| D|--------12-----------11-----------9-----------7----| A|-----0------------0------------0-----------0-------| D|--0------------0------------0-----------0----------| d|----------------------0-----------------------0----| A|----------0-----------------------0----------------| G|-------0-----------0-----------0-----------0-------| D|----0-----------0-----------0-----------0----------| A|---------------------------------------------------| D|-5-----------4-----------2-----------2-------------| And that's it for the intro, and a large portion of the song basically.
