A Locrian Scale on Irish Bouzouki

Play the A Locrian scale on Irish Bouzouki with fretboard diagrams that map the pattern across the neck. The Locrian scale has 7 notes per octave and belongs to the modes family.

Irish Bouzouki's tuning sits inside this one: all 3 open courses are scale tones and one of them is A itself — G (the flat 7th), D (the 4th), A (the root). Open-course drones cost nothing here. Open, the courses cover G3 to D5.

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.

Irish Bouzouki is tuned G–D–A–D, with 15 frets to work with. Voicings are computed for this tuning by the shared voicing generator, not borrowed from another instrument; traditional technique may still use idiomatic shapes not charted here.

Each position shows the scale notes and their intervals from the root so you can connect the shape to its sound, hear it with audio playback, and practice it in any register. Movable patterns let you transpose the same fingering to other keys once it is learned.

Once a position is under your fingers, link the A Locrian scale to the chords it harmonizes and to progressions in the key of A to start improvising and writing with it. Working a scale alongside its chords is the fastest way to make it stick and to hear how it colors a progression.
