What is the C# Locrian ♮2 Scale?
Locrian ♮2 is the sixth mode of the melodic minor scale, and it solves a practical problem: standard Locrian's ♭2 clashes badly with the root over half-diminished chords, but this version keeps a natural 2nd. It's the preferred scale choice for m7♭5 chords in modern jazz, giving you all the darkness of Locrian without the harshest dissonance. Here's how the C# Locrian ♮2 Scale lays out on the fretboard. This scale is enharmonically equivalent to Db Locrian ♮2.
Notes and Positions
Locrian with a natural 2nd; 6th mode of melodic minor. Used over half-diminished chords in jazz. On guitar, the same scale tones repeat in multiple positions, so the real goal is learning how to connect shapes up and down the neck. Use the CAGED boxes as smaller practice areas before linking the full fretboard. In the key of C#, the notes are: C#, D#, E, F#, G, A, B.
How to Use It
You'll often hear it in Jazz, Fusion, and Half-diminished chords. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.
Alternate between ascending patterns and short musical phrases so it doesn't become a "scale exercise" only. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
