Althea
Notes:
You can think of Althea as being in either B dorian or E mixolydian…it amounts to the same notes either way. What’s more important is targeting the chord tones of each chord as they go by.
Regarding the diagrams on this one, at the beginning, you’ll see the scale diagrams for the 1st position on the fretboard. At about the 2:00 mark, the diagrams will change to the 4th position, and then they’ll change again every 2 minutes or so, gradually working up the neck.
