5 h 8 t 12, index on the 5, middle or ring on the 8, right hand index or middle on the 12th. Hammer on the 12 with your left hand (tap), then pull off to the 5th fret(your left index.) Now hammer on the 8th fret, then hammer with your left hand index on the 12th fret. When pulling off, adding a little downwards pressure will help to sound it better. It might not sound right at first, but once you get up to speed, it'll knock your socks off.
