G locrian scale — chords and intervals
The harmonized G locrian scale generates the most unstable chord family of all the modes, with a diminished tonic chord that provides no sense of rest. This makes Locrian harmony a specialized tool for creating extreme tension. The chords of G locrian are Gm7b5, AbMaj7, Bbm7, Cm7, DbMaj7, Eb7, Fm7. In practice, Locrian chords are used over half-diminished passages in jazz rather than as a standalone key. The i°-bII movement creates a restless, searching quality useful for transitional sections and building suspense. Commonly used in Jazz, Metal, Experimental, Avant-Garde. Notable players include John Coltrane, Meshuggah, Dream Theater.

Degree-by-Degree Analysis
The I chord (Gm7b5) is the tonic — the gravitational center of the key. The ii chord (AbMaj7) is the minor subdominant, commonly used to approach the V chord. The iii chord (Bbm7) functions as a substitute for the I or vi. The IV chord (Cm7) is the subdominant — it adds motion and moderate tension. The V chord (DbMaj7) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (Eb7) is the relative minor — it brings emotional color and depth. The vii° chord (Fm7) is the diminished — the most tense, rarely used alone, usually leading to the I.
