B Locrian — Bass VI

The B Locrian scale runs 7 notes per octave in the modes family. Below it sits on the Bass VI's EADGBE strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

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.

Because the Bass VI carries guitar tuning an octave down, these patterns are guitar geometry with bass consequences — watch the G-to-B string crossing, where the shape bends by one fret.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in B and let the scale turn into lines.
