Brilliant. The tutor Ive been looking for.

Clean interface. You are able to isolate the sections you are weak on and really drill them.
Ive made more progress reading note position and identifying notes on the fretboard in 1 day than I did with a year of reading music books.
A must have if you have zero short term retention memory like me.

To the author, if you could make an app in the same vein that drilled songs I would certainly be first on the list to buy it.
