this is a very cool intro that i learned when i was playing around on my guitar
standard tuning (e,B,G,D,A,)
e---9-9-9-9--7-7--5-5--7--9-9-9-9--7-7--5-5--7----------------------------------
[B-]--9-9-9-9--7-7--5-5--7--9-9-9-9--7-7--5-5--7----------------------------------
[G-]--9-9-9-9--7-7--5-5--7--9-9-9-9--7-7--5-5--7----------------------------------
[D-]------------------------------------------------------------------------------
[A-]------------------------------------------------------------------------------
[E-]------------------------------------------------------------------------------
i noticed that the 9-9-9part goes pretty fast so play it that way
