Intro: G# minor
The bassline moves chromatically from G# to F#, and then back again. So if you do
like this you can get it:
D|-6-5-4--4-5-6-| (listen to the track for the rhythm)
But personally I don't bother since you need to strum it funny and it's hard to get
(but if you're playing this with a bassist, you're in the money).
