follow the pattern of the 12 bar blues which is

a   a   a   a   d   d   a   a   e   d   a   a   
1///1///1///1///1///1///1///1///1///1///1///1
4 beats to each bar but i don't know how to write the bars on my computer but
thats the pattern.The a stands for riff a, d stands for riff d, and e stands
for riff e.

I'm only 14 so go easy on me if its wrong but i'm sure its right!
