Very, very easy considering it's just four chords repeat throughout the whole song.
the bum-bum bum-bum da-dum dum part in the song.. if you try and sing with it, it might seem 
little difficult, just to warn you). Here are the tab and chords:


p = pull off (you can chose to slide if you'd like or even play the two notes separately)

E|-----------------------------|
B|-----00-233-----00-2---------|
G|---22---------22----22-2p1---|
D|-44---------44---------------|
A|-----------------------------|
E|-----------------------------|
