G 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: E (bb7), the double-flat seventh that makes this the darkest mode of harmonic minor.

tip
  • Use G ultralocrian over a diminished 7th chord: the double-flat 7th (E) is the chord's own diminished 7th, spelled into the scale.
  • It is harmonic minor's seventh mode: play G 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 (Ab), b4 (B) and b5 (Db); there is no darker mode in the harmonic minor family.

How to play G ultralocrian on guitar

Open G doubles the root, so a drone sits under this key from the first strum. Low E, A, B, and high E all keep contact with the scale as well, respelled Fb, Bbb, and Cb along the way. E-shape barre: fret 3. Diatonic harmony supplies Abm, Dbm, and Cbaug yet never a functional dominant, which means resolving to the tonic takes a workaround.
