Riff 1 (played 1st and 3rd times):
e---0--------2--------0--------2-----
B-----2--------3--------0--------3---
G-2-----2--2-----2--1-----1--2-----2-
D------------------------------------
A------------------------------------
E------------------------------------

The above riff is played with pick and the 2nd (middle) and
3rd (ring) fingers such that the pick plays the G string, the
2nd finger the B string and the 3rd finger the e string.
Alternatively, you could use just fingers with thumb, index
and middle fingers but it makes changing to chords difficult.
