Continuing my look at Melodic Minor modes this post covers mode 6, Aeolian b5. This mode is also known as the Locrian ♮2 (or ♮9).
Scale formula
The formula for the Aeolian b5 scale is:
R - 2 - b3 - 4 - b5 - b6 - b7
Chords
- min7b5
- min7b5♮9
Possible extensions/tensions: 9, 11, b13
You can make a min7b5♮9 chord by taking a standard min7b5 chord and dropping the b3 a semitone.
