G# Locrian Scale — Notes and Intervals
The G# Locrian scale is the seventh and most unstable mode of the major scale. On Piano, the notes are G#, A, B, C#, D, E, F#. 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 G# Locrian are G#m7b5, AMaj7, Bm7, C#m7, DMaj7, E7, F#m7. 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.
