Standard Tuning, This song is really easy, and it sounds better with a Pick(or at least 
the beggining does) Whether or not this is correct doesnt matter, it sounds fine with 
the song, so rock on and go for it



(This is the Verse, but on the intro play it with a pick or usign your two fingers going 
REALLY fast but just gently touching the string so it gets that soft sound)
