I highly doubt that Doc Simon would put erroneous info in his lessons but then again everyone makes mistakes. I still think it's right and it definatly sounds right to me. As far as I know that is a Phrygian scale. You could always PM Doc Simon about it.

If you use both of those links together you can see where each mode begins and ends. In the scale chart it has Doc Simons Phrygian mode the way it is so I'm guessing the lesson is correct. To find out where you are use the red numbers at the top. They are the fret numbers just like the dots on a guitar.
