Sound

A Locrian variant with an unexpected natural 6th that creates an augmented 2nd gap. Harsh and exotic. the ♭2 and ♭5 keep it dark, but the natural 6th adds an angular, unexpected brightness.

Practical Use Cases

  • Over m7♭5 chords in harmonic minor contexts
  • ii chord in a harmonic minor ii-V-i
  • When the harmonic context specifically implies harmonic minor

Practical Notes

This is the second mode of harmonic minor. It's another option for m7♭5 chords, but the natural 6th creates an augmented 2nd interval that can sound awkward in melodic lines. Most jazz players prefer Locrian ♮2 (from melodic minor) for half-diminished chords. Use this one when you're specifically thinking in harmonic minor. for example, if the whole progression is clearly in a harmonic minor key. Otherwise, Locrian ♮2 is usually smoother.
