Continuing my look at Melodic Minor modes this post covers mode 5, Mixolydian b6. This mode is rarely used so this post will be short. It’s included for completeness rather than anything else.
The formula for the Mixolydian b6 scale is:
R - 2 - 3 - 4 - 5 - b6 - b7
- Dominant 7b13
Possible extensions/tensions: 9, 11, b13
Rarely – if ever – used.
