Oh, I see, thanks. It looks like you titled each line like, "I" for intro, "V" for Vamp, "Ch" for chorus. I think I got it. This is a good "mixed" system. The fact that you mixed in the beats by notation is pretty advanced(quarter notes[1,2,3,4]). You would have to be able to read music and understand theory to play this peice. I think I would have to start with a purely progression pattern.
