G----------------------------------|
D----------------------------------|
A-------------1-0-------------1-0--|
E-1-1-3-1-4-1-----1-1-3-1-4-1------|

For those of you who like to go up an octave

G-----0---1---3-2-----0---1---3-2--|
D-3-3---3---3-----3-3---3---3------|

A-----------------3-3--------------|

E---1-1-1-1-1-1-1------------------|

Repeat the former pattern

Then on the hits at the end
