F# Locrian Scale on Mountain Dulcimer

Play the F# Locrian scale on Mountain Dulcimer with fretboard diagrams that map the pattern across the neck. The Locrian scale has 7 notes per octave and belongs to the modes family.

All 2 of Mountain Dulcimer's open strings fall inside F# Locrian — D (the flat 6th), A (the flat 3rd) — though F# itself has to be stopped. Open, the strings cover D3 to D4.

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.

Mountain Dulcimer is tuned D–A–D, with frets 1 to 17 laid out diatonically plus the 6+ and 13+ frets — D#, F and A# sound nowhere on it. Only the chords and notes its diatonic frets reach are charted, and the 6+ fret (between 6 and 7) counts as a fret of its own.

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. The Mountain Dulcimer's frets are diatonic, so the pattern does not slide to other keys: each key sits on its own set of frets, and only the notes those frets reach are charted.

Once a position is under your fingers, link the F# Locrian scale to the chords it harmonizes and to progressions in the key of F# 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.
