1)He descend the scale like this :
g-16-13-16-14-16-13-16-11-16-14-9-16-11-7-16-9-etc..|
2)Ascending the scale :
g-16-2-16-4-16-2-16-6-16-4-16-7-16-etc.|
3)The fast octave part :
g-16-14-16-2-16-14-16-2-|
4)Then he does something like this (no tapping here):
g-4-2-----------------------2-4--|
D-----4-2--------------2-4-------|
A----------4-3-2-3-4-------------|
5)Ascend the scale like (2)
6)Then play around with these patterns:
e-16-9-12-----------|
b----------16-9-10--|
e-16-7-9-----------|
b----------16-7-9--|
e-16-5-7-----------|
b----------16-5-7--|
e-16-2-4-----------|
b----------16-2-4--|
All 16's here are tapped , and rest of the notes are legatos (hammers/pulloffs/slides).
