This lesson is designed to help you shift from one position to the next within the modes. I created the sequence in G because it starts low on the neck and doesnt end too high to fit in the composer. In the first position you are playing the G ionian mode. When you reach the highest note in that position you descend in the A dorian mode. Then when you get to the bottom of that scale you shift up to B phrygian and so on and so forth.
