Not very difficult, Kinda like jazz.

At the guitar riffs-

e------------------------------------------------------------------------------|
D-------------------------------------------------------------  <--This is 12--|
A-------------------------------------------------------------  Times for 0-00-|
E--0-00-0-00-0-00-0-00-0-00-0-00-0-00-0-00-0-00-0-00-0-00-0-00-----------------|

Then during the chords play-
e-------------------------------------------------------------|
D-------------------------------------------------------------|
A--------5-55------3-33-------5-55----------------------------|
E---5-55------3-33-------5-55------3-33-3-33------------------|

And finally same as top but changes a little, Listen for the difference.
e-------------------------------------------------------------|
D-------------------------------------------------------------|
A------------------4-44-4-44-4-44-4-44------------------------|
E--0-00-0-00-0-00---------------------------------------------|

You have to listen for the changes to continue the 0-00 or to change
but these are the notes so have fun. If you have trouble Im sorry this is my first tab.
