B ultralocrian

The ultralocrian scale is the seventh mode of the harmonic minor scale: locrian with its 4th and 7th squeezed down further, leaving a diminished 7th chord spelled straight up the scale. Everything in it wants to collapse inward, which makes it a natural over diminished 7th chords and the darkest corners of metal and jazz vocabulary.

it consists of these notes and degrees:

Characteristic note: Ab (bb7), the double-flat seventh that makes this the darkest mode of harmonic minor.

Same notes, different mode

tip
  • Use B ultralocrian over a diminished 7th chord: the double-flat 7th (Ab) is the chord's own diminished 7th, spelled into the scale.
  • It is harmonic minor's seventh mode: play B a half step up in harmonic minor fingering and you are already here.
  • Everything wants to fall; resolve the whole line down a half step into the major or minor chord below.
  • For extreme metal color, pedal the open root against b2 (C), b4 (Eb) and b5 (F); there is no darker mode in the harmonic minor family.

How to play B ultralocrian on guitar

Open B sits on the root with open G at the minor sixth, so two strings drone in-key immediately. A string picks the root up at fret 2, with both E strings following at fret 7 and the D string at fret 9. Capo at fret 2 and the whole key reads as A fingering, which lets nut-position shapes come along. Harmony gives Cm, Fm, and Ebaug.
