Anders is away for a it so thought I would try this question here. In one of his blues lessons he talks about finding the root note in the places in the A minor blues scale and how you can (should?) start and end your lick on the root. While he shows us where the root is in the spots on the scale, I am wondering how to find it in other scales. Is it always found by ear (will be hard for me) or is it always a certain number of intervals (not sure thats the right term) away from the first root?
