Harmony first
Where this scale fits.
ChordRevelation treats scale choice as a relationship between chord formula, function and target — not as a root-name lookup.
Minor ii–V–i
Minor ii–V–i
Locrian-family material is a natural starting point over iiø before a dominant resolves to minor tonic.
Context-sensitive ♭2
Context-sensitive ♭2
The ♭2 can be altered to natural 2 in other half-diminished systems, so harmonic context matters.
Fretboard practice
Turn the formula into usable guitar vocabulary.
Keep chord tones visible, compare overlays and practice toward the next chord instead of running patterns without a harmonic destination.

1–♭2–♭3–4–♭5–♭6–♭7
How should I practice locrian mode on guitar?
Connect the interval formula to chord tones and real harmonic context, then compare positions on the fretboard instead of memorizing a single box.
Can I use locrian mode over every chord with the same root?
No. Scale choice depends on chord quality, harmonic function, key context and the next target chord, not only the root name.
