a. These eight notes should be played as quickly as possible. If you can't
get the fingering right, try them on a different string, or just play the
fourteenth fret, eight times.
b. This is accurate. Slide from the fifth fret, all the way to the nineteenth
for a measley two notes. If it's a little too far to make, then just play it
on another string.
c. After letting the second fret ring out for a short time, you should
lightly flcik the ninth, and slide it down. If you listen to the song,
you'll hear it.
That's all. Hope this was of some help to you. If you thought it was
rubbish, tell me. If you thought otherwise, I'd like to hear that too :)
