F♯ locrian (F♯, G, A, B, C, D, E) has one sharp in its key signature and its diminished 5th (C) creates the unstable, dissonant character of the locrian mode. It is used over F♯m7♭5 chords in jazz, particularly as the ii chord in E minor ii–V–i progressions. F♯ locrian is extremely rare outside jazz.
Locrian is the only mode with both a flattened 2nd and flattened 5th, creating a diminished tonic chord that resists resolution. These two intervals produce maximum harmonic instability — the sound of tension without release.
The seven diatonic modes — parallel modes starting from the same root with different interval patterns. Each mode has a unique character derived from the major scale.
The diatonic chords in F# Locrian are: F#dim, G, Am, Bm, C, D, Em. These are the chords built naturally from each degree of the scale.
