Here?s a cool guitar line, usually arranged for piano or something in
a symphony made by norwegian Grieg. It?s really cool to play anyway.

Begin playing these two lines pretty slow.

e----------------------------------------l
b----------------------------------------l
g----------------------------------------l
d----------------------------------------l
a--------0-2---2--1---1--0---0-----------l
E--0-2-3-----3------2------1-------------l

e----------------------------------------l
b----------------------------------------l
g----------------------------------------l
d-----------------2-0--------0-----------l
a--------0-2---2------2----2-------------l
E--0-2-3-----3-----------3---------------l

Then play it faster and faster until you just can?t move your grip
fast enough to continue playing.
