This mode is just like the Dorian mode but the second is lowered. But because of this change, it is a lot harder to play this over minor chords so this mode isn't used very often.

By stacking 3rds above the root, we get a series of minor sounding chords:
1-b3-5= Minor Triad
1-b3-5-b7= Minor 7
1-b3-5-b7-b9= Minor 7b9
1-b3-5-b7-b9-11= Minor 11b9
1-b3-5-b7-b9-11-13= Minor 13b9
Other possible minor chords.
1-b3-5-6= Minor 6
1-b3-5-b7-11= Minor 11
1-4-5= Sus4
1-4-5-b7= sus7
1-b3-5-b7-11-13= Minor 13
The fingering patterns for this mode are the same as the Dorian mode except the second is flattened
Dorian b2 Vamp: It's a good idea to resolve the minor 9th to the root when soloing over this vamp.
Vamp #1: (Gm6/Gm7) (Use G Dorian b2)
