And, here we are with mixolydian and locrian modes. For those of you trying to remember all of these scales and the interval system, I find it useful to think of it based on the C Major (Ionian) interval system.
Interval Pattern of Whole and Half steps:
C Major (Ionian) – W W H W W W H
C Dorian – W H W W W H W (notice the relationship to Ionian)
C Phrygian – H W W W H W W (notice relationship to Dorian)
C Lydian – W W W H W W H
C Mixolydian – W W H W W H W
C Aeolian (Natural Minor) – W H W W H W W
C Locrian – H W W H W W W
