F# Locrian Scale — Notes and Intervals
The F# Locrian scale is the seventh and most unstable mode of the major scale. On Mandolin, the notes are F#, G, A, B, C, D, E. It sounds highly dissonant and unresolved, as its home chord is a diminished triad. While rare as a primary key, it is a crucial technical tool for jazz musicians improvising over half-diminished chords in tension-heavy passages. The diatonic chords of F# Locrian are F#m7b5, GMaj7, Am7, Bm7, CMaj7, D7, Em7. Commonly used in Jazz, Metal, Experimental, Avant-Garde. Notable players include John Coltrane, Meshuggah, Dream Theater. Use over m7b5 (half-diminished) chords. Essential for jazz ii-V-i in minor keys where the ii chord is half-diminished.
