For the intro I had to use drop C, this doesn't sound much like Air as I know
them but an octave higher on the intro just sounds wrong. Obviously it's still
the same notes - just higher - so you can play it like that if you want. I
reckon he's using a five-string, which I haven't got and it's only the intro
that uses the fifth string anyway.
Check at the bottom for the order of play.
/ = Slide up
= Slide down
\ = Slide down slowly
r = Let the note ring
