The other three arpeggios!
D Major (Mixolydian) (5 - 4 - 3 - 1)
E Minor (Aeolian) (5 - 4 - b3 - 1)
F# Diminished (Locrian) (b5 - 4 - b3 - 1)
As you may have noticed our D Major is the same shape as our G major from the last video and our E Minor is the same shape as the other two minors.
I'm not sure if I've ever heard a Diminished sus4 chord ;-p but the purpose was to expand this idea throughout the entire key. ;-)
