Modal character

A Locrian is the 7th mode of B♭ Major — the same seven notes started from its 7th degree.

1 ♭2 ♭3 4 ♭5 ♭6 ♭7

Characteristic note — flat 5th (♭5). The ♭5 makes Locrian the only mode built on a diminished tonic triad — the most unstable of the seven and rarely used as a key center.

Locrian is the mode of the half-diminished (m7♭5) chord and is most useful over the iiø of a minor ii–V–i. Its restless quality comes from the ♭2 and ♭5 that frame the root.
