NOTE:
This is a simple beat that i figured out just messing around  on my acoustic. 
It can provide hours of fun if you jest change it around and improvise the rhythm and strum/pick patterns.

MAIN CHORDS.  improvise strum pattern.

   1  2  3  4  5  <chord #
[--0--0--0--0--0-]
[--3--0--0--0--0-]
[--2--0--0--0--0-]
[--0--0--0--2--0-]
[--0--3--2--3--0-]
[--0--0--3--0--2-]


order played in verse
 1, 2, 3. you can change the pattern to fit your style. 
I like to hit the #3 chord three or four times after the 1 and 2 chords.
 
order played in chourus
3, 4, 3, 5. again, you can change the pattern to fit your style.
I also like to hit the #5 chord three or four times.

This is just a basic rhythm to get you started.  
It has easy add ons and fits well with almost anything. There is also an intro that
that is pretty fun to play

INTRO Here goes:

[---------666666666-9-9-8-6------------------------]
[-----6-8-666666666---------8-6--------------------]
[-6-7---------------------------7-6----------------]
[-----------------------------------8~~~~----------]
[--------------------------------------------------]
[--------------------------------------------------]
 
This sorta has a bluesy sound to it. To play it best, strike it with a swinged 
long, short, long, short pattern.
