~ = vibrato

Not a whole theme in particular, but the high-pitched riff that keeps showing up time and time again. If you want to just play that cool acoustic rhythm in the background, then fingerpick [Am], [Bm], and [Bbm]. As for the guitar solo in the main theme... well, definite brownie points to whomever can send me that tab :)

(pick the blue notes lightly)

B = bend

Spine-chilling theme from the Maestro himself. Adheres to the A harmonic minor scale, which makes it rather user-friendly.
