This mode suggests a minor sound due to the b3rd and b7th pitches. However, the b6 and b5 cause tension in minor chords.
By stacking 3rds above the root, we get a list of minor chords:
1-b3-b5= Diminished Triad
1-b3-b5-b7= Minor 7b5 (AKA Half-Diminished)
1-b3-b5-b7-9= Minor 9b5 (rare)
1-b3-b5-b7-9-11= Minor 11b5 (rare)
1-b3-b5-b7-9-11-b13= Minor 11b5b13 (very rare)
Respelling the b6 as #5 will produce other types of minor chords:
1-b3-#5= Minor #5
1-b3-#5-b7= Minor 7#5
1-b3-#5-b7-9= Minor 9#5
1-b3-#5-b7-9-11= Minor 11#5
The most useful chord from the first harmonization of this mode is the minor 7b5. From the second harmonization, the Minor 7#5.
For this vamp, stress the chord tones (1-b3-b5-b7) over the first chord and the b6(#5) over the second chord.
Vamp #1:(Gm7b5/Gm7#5) (Use G Locrian #2.)
