What color?

Locrian whose seventh is doubly lowered (bb7), turning the half-diminished into a dim7 color. A rare mode from harmonic major, dark and unstable, that opens an unexpected angle on a diminished chord.

Origin & history

The seventh mode of the harmonic major, diminished in its upper part. A theoretical construction, to be reserved for exploration.

Which chords to play it on?

Outside the functional consensus: this is an exploration color. Lay it over a vamp or a held chord to tint your improvisation with an unexpected flavor, rather than inside a cadence.
