Hi this is basically crazy train intro riff higher up and faster so it was quite easy 
me to transcribe .

This is the main riff of the song played the whole song.

Tuning=Standard    E A D G B E

E---------------------------------------|
A---------------------------------------|
D----------------------------------3----|
G-0--0---0---0----0-1-------1--------0--|
B------3---4----3-----3-2-3---3-2-------|
E---------------------------------------|

This riff riff is repeated over and over again.


The speed isn't too difficult once your fingers know the notes so start off slow then 
up the speed.

Enjoy :)
