Tuning: Standard - 440 Concert Pitch As usual there are two guitars in this song, one electric and one acoustic. And while I'm fairly certain that the acoustic is playing the Dsus2, the electric may be doubling him with a straight D chord. If you play this on one guitar you can try alternating between the Dsus2 and the D with a quick hammer on. Varies the sound a bit and isn't so monotonous.
