F Locrian 𝄫7 Scale
F Locrian 𝄫7 contains 7 notes: F, G♭, A♭, B♭, C♭, D♭, E𝄫. It has 5 flats: G♭, A♭, B♭, C♭, D♭. The step pattern is H–W–W–H–W–H–W+H.
A Locrian variant with a double-flat 7th that pushes diminished darkness even further. The bb7 is enharmonically a natural 6th, creating an interval paradox between notation and sound.
The formula is 1, b2, b3, 4, b5, b6, bb7. The bb7 (enharmonically a natural 6th) creates an interesting duality: the scale sounds almost like Locrian natural 6 from harmonic minor but is notated differently in context. This distinction matters for proper voice leading in harmonic major contexts.
Primarily theoretical. When it appears in harmonic major progressions, treat the bb7 as a passing tone that resolves by half step. Understanding this mode helps complete the picture of harmonic major's modal system.
