This is the first tab i've tried to figure out and actually submit, but not sure if it's
correct, but here ya go:
[ Tab from: http://www.guitaretab.com/a/avantasia/116566.html ]
E-----------------------------------------------------------------|
B-----------------------------------------------------------------|
G--6-7-4-6~----6-7-4-6---10-8~--6-7-4-6~---6-7-4-6--10--8---12~---|
D-----------------------------------------------------------------|
A-----------------------------------------------------------------|
D-----------------------------------------------------------------|
E---------------------------------------------------------------| x2
B---------------------------------------------------------------|
G--6---6--4-6-7-6--6-----4-6-7-6---6--4-6-7-6-6---10-9-7--------|
D---------------------------------------------------------------|
A---------------------------------------------------------------|
D---------------------------------------------------------------|
You can also alternate this pattern in the tab to different frets and it still sounds pretty good.
