i know u are really trying hard, to break this down for me. But either im stupid (which some people think i am), or there is a error in this scale http://www.guitartricks.com/lesson.php?input=8093
in the 3 scale, should it say,
A string 12,13,15 instead of 12,14,15

anyway's in this link http://www.jamsess.com/test/guitar.phtml
i can't figure out, how u can see where to start and where to stop.
