F# Locrian — Chicago Tuning Banjo

F# Locrian is 7 notes to the octave (modes family), drawn here across the Chicago Tuning Banjo's DGBE strings with every F# marked, so home stays visible from anywhere in the pattern.

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.

Because these four strings are the guitar's top four, patterns a guitarist already owns land here unchanged. The work is rhythmic rather than geographical: making the pick articulate every note the head refuses to sustain.

Run it against a click at a tempo where every note gets the same weight. On a banjo an uneven scale is audible immediately — the instrument gives you no sustain to hide behind.
