G Locrian in Baritone (B Standard) — Notes and Intervals
The G Locrian scale is the seventh and most unstable mode of the major scale. On Guitar, the notes are G, Ab, Bb, C, Db, Eb, 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 Gm7b5, AbMaj7, Bbm7, Cm7, DbMaj7, Eb7, Fm7. 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.

About Baritone (B Standard) Tuning
The baritone guitar is tuned a perfect fourth lower than standard guitar (B-E-A-D-F#-B), producing a distinctly beefy tone with serious low-end depth that sits perfectly between guitar and bass. Its rich, dark voice has made it a secret weapon in film scoring, ambient music, and moody songwriting where you need that unmistakable low-end warmth without losing clarity.
Unlike simply tuning a standard guitar down (which causes floppy strings and muddy tone), the baritone guitar uses a longer scale length (typically 27"-30") designed specifically for lower tunings. This gives each note clarity and definition even in the lowest register. Session musicians, film composers, and bedroom producers alike reach for the baritone when they need dark, atmospheric textures, doom-laden riffs, or simply a different sonic palette that standard guitar can't deliver.
Notable artists: Pat Metheny, Nels Cline, Brian Setzer, Baritone session players in Nashville
Best for: Moody songwriting, film scoring, ambient textures, doom metal, and any production that needs low-end depth with clarity
Musical Character
The only mode with a diminished 5th (b5) from the root, making its home chord a diminished triad. This instability means Locrian is almost never used as a key center — it is a tool for tension.
