The C Locrian scale is the seventh and most unstable mode of the major scale. On Guitar, the notes are C, Db, Eb, F, Gb, Ab, Bb. 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 C Locrian are Cm7b5, DbMaj7, Ebm7, Fm7, GbMaj7, Ab7, Bbm7. 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.

How to Play C Locrian on Guitar
Place your index finger at fret 8 on the 6th (low E) to find your C root note. Use a three-notes-per-string fingering to cover the full scale in one position, or learn the CAGED shapes to navigate the entire fretboard. An alternative starting point is open position.
The C Locrian scale contains 5 flats (Db, Eb, Gb, Ab, Bb). Its relative major is Eb major, which shares the same key signature.
