now take the modes and put them in a differnt order (western civilization did, they changed what the greeks had).
NEW ORDER FOR MODES HALF STEPS
!&8 = LOCRAIN 1-2 & 4-5
2 = Phygrain 1-2 & 5 &6
3 = aeolian 2 -3 & 5- 6
4 = Dorian 2-3 & 6-7
5 = mixolydian 3-4 & 6-7
6 =Ionian 3-4 & 7-8
7 = Lydian 4-5 & 7-8
8 or 1- back to Locrian the beginning
Now try it out in any mode exp. D Locrain =C#D E F#G A B >1-2 & 4-5 and so on and on.

Am I crazy? :p
