Here is a song I made up when I was bored
It is very simple but I think it sounds good

You play it at a very fast past


I--2-2-2-2-2-2-2-2-2-2--1-1-1-1-1--0-0-0-0-0--0-0-0--0-0-0--------I
I--3-3-3-3-3-3-3-3-3-3--0-0-0-0-0--1-1-1-1-1--0-0-0--0-0-0--------I
I--2-2-2-2-2-2-2-2-2-2--0-0-0-0-0--0-0-0-0-0--2-2-2--1-1-1--112--I
I--0-0-0-0-0-0-0-0-0-0--0-0-0-0-0--0-0-0-0-0--0-0-0--0-0-0--------I
I-----------------------------------------------------------------I
I-----------------------------------------------------------------I

And repaet as many times as you wish
I think it would at least be a good background to a song
Enjoy
