you want to keep the shape all the way through the sequence, the
shape is
E-----|
B----9|
G----9|
D----7|
E----8|

e-----------------------------------------------------------------|
B-----------------------------------------------------------------|
G------9---------------9------------------------------------------|
D----9---9---9---9---9---9---9---9--------------------------------|
A--7-------7---7--------------------------------------------------|
E------------------8-------8---8----------------------------------|

BTW don't bother stealing this,
But do feel free to use it as a picking exercise
