Mandolin Fills With G Locrian

G Locrian runs 7 notes to the octave. Below it is laid onto this chair's GDAE fretboard with every G marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.

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.

A mandolin fill is short and often tremolo-doubled, so the scale here is a source of two- and three-note runs between the vocal phrases, not a ladder to climb.

Play it slowly against the audio until the shape stops being a shape, then take it to a song in G and let the melody pick its own notes out of it.
