not entirely sure whether this intro is totally right or not, I'm guessing they
play in Drop D or something to make it sound a bit heavier with the distortion,
but on the B (fret 7) there's something else going on, either a couple of muted
chords of a quick change back a fret, I think it sounds closer with a few muted
strings.
oh and it's just an estimation of how many times the bloke plays the chords, so
don't play exactly 8 strums on each, listen to the song and work out the pattern.

the 4 on the B string at the end is played to show the riff being repeated, the
times when the verse/chorus or whatever comes after you just end on the 7.

there's a bit just after this that I don't know, and can't really be
bothered to work out.
