I just want to mention, if it's not to obvious. That this method of making charts is a very good tool to have in ones grasp and still done far and wide even as in ancient times. i don't read and play though I'm quite a fair sight singer. To transmit the info in your head to other players you gotta figure somethin' out. It doesn't have to be fancy to get the idea out there. I supply the rest if the info with body english.
