G Minor Locrian Scale — Notes and Intervals
The G Minor Locrian scale provides a smoother approach to half-diminished chord improvisation by raising the second degree of standard Locrian. On Bass, its notes are G, A, Bb, C, Db, Eb, F. Jazz musicians rely on its natural second for elegant voice leading over m7b5 chords in minor ii-V-i progressions, where pure Locrian would sound too angular. Commonly used in Jazz, Post-Bop, Fusion, Progressive. Notable players include John Scofield, Wayne Shorter, Kurt Rosenwinkel. Use over m7b5 (half-diminished) chords. The natural 2nd provides smoother voice leading than standard Locrian while retaining the essential b5. Preferred by jazz musicians for minor ii-V-i progressions.

How to Use the G Minor Locrian Scale
Use over m7b5 (half-diminished) chords. The natural 2nd provides smoother voice leading than standard Locrian while retaining the essential b5. Preferred by jazz musicians for minor ii-V-i progressions.
Origin & Background
Functionally equivalent to Locrian #2 (the 6th mode of melodic minor). Jazz improvisers developed this as a practical alternative to standard Locrian, whose b2 created awkward voice leading over half-diminished chords. The natural 2nd degree smooths out the melodic contour while preserving the characteristic b5.
How to Play G Minor Locrian on Bass
On bass, locate G on the E string at fret 3. Use a one-finger-per-fret approach starting from the root and span two to three strings. Keep your fretting hand relaxed and practice shifting between positions cleanly.
The G Minor Locrian scale contains 3 flats (Bb, Db, Eb). Its relative major is Bb major, which shares the same key signature.
Practice Routine — Exercises for Playing
Practice the G Minor Locrian scale by playing it ascending with one rhythmic feel (straight eighth notes) and descending with another (swing or triplets) at 100 BPM. This dual approach trains both technical accuracy and rhythmic versatility with the 7 notes of the scale.
Experiment with simple two-chord vamps rooted on G to let the characteristic intervals of the Minor Locrian scale come through clearly. This scale is especially effective in post-bop contexts.
Bass Tips
On bass, use the G Minor Locrian scale to build walking bass lines by targeting chord tones on strong beats and using scale tones as approach notes. This is the foundation of functional bass playing. Aim for a dark quality in your phrasing to match the natural character of this scale.
