B Locrian — Resonator Guitar

B Locrian is 7 notes per octave (modes family), drawn here as position boxes on the Resonator Guitar's GBDGBD grid with the root flagged in each — learn one box deeply, then let the overlaps carry you into the next.

The most dissonant, unstable mode — the tonic chord is diminished (b5), making a true Locrian tonal center rare. Used for color and passing harmony.

Heard in: Metal riffs, jazz (half-diminished ø7 chords in ii°7 – V – i), horror and tension film scores.

In open g the same letters repeat across the strings, so scale maps here look nothing like standard-tuning boxes — follow the drawn frets, not habit.

Play each box top to bottom until the roots feel like home base, then practice crossing between boxes mid-phrase — neck freedom is exactly that crossing, nothing more.
