C Locrian 𝄫3 𝄫7 Scale
C Locrian 𝄫3 𝄫7 contains 7 notes: C, D♭, E𝄫, F, G♭, A♭, B𝄫. It has 3 flats: D♭, G♭, A♭. The step pattern is H–H–W+H–H–W–H–W+H.
The most extreme Locrian variant in the double harmonic family. With double-flat 3rd and double-flat 7th on top of Locrian's already dark framework, it represents the absolute limit of flattened degrees.
The formula is 1, b2, bb3, b4, b5, b6, bb7. This mode pushes every interval to maximum flatness within a heptatonic context. The bb3 and bb7 produce enharmonic paradoxes that challenge conventional notation. It exists primarily to complete the theoretical picture of the double harmonic modal system.
Purely a theoretical tool and brief chromatic color. If you use it at all, treat it as a passing texture lasting no more than a beat or two before resolving to something stable.
