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 Intro G:------------------------------- G:-------------------------------- D:------------------------------- D:-------------------------------- A:------------------------------- or A:--7--7-5--7-7/107--7--7-5
