Its color

Locrian has a flat second and, above all, a diminished fifth: here F. Its root chord is diminished, so it’s unstable: that’s why it’s rare in practice. It has the same notes as the C major scale, but starts on B.

Which chords to play it over

It goes over a half-diminished chord (m7♭5), which the site doesn’t cover yet. To hear it, try the C, Em, C, Em progression while aiming for B.

Where you hear it

Rarely: a few metal riffs and experimental music. Often-cited example: “Army of Me” (Björk).
