Thanks. As I look more closely, I think the problem is with the notation. The notes are written as (low to high): Db, G, Ab, E, F.
Thanks for fixing it. The site and all the materials - the app and book- are really amazing resources. I am learning a lot and getting great enjoyment out of playing the lessons. There is nothing else out there that even comes close to FlamenconExpalined in regard to quality and comprehensive approach to the art of flamenco guitar.
