C Locrian is the natural minor with the b2 and b5 — Db and Gb. Those are the notes that give it its character.
What is C Locrian?
C Locrian is the seven notes C Db Eb F Gb Ab Bb — the notes of Db major started from its 7th degree, C. Same seven notes as the parent, but with C as home, so the intervals and the sound are different.
C Locrian vs C natural minor
5 of the seven notes are the same. The difference is 2 notes, and that is the whole character of the mode:
- b2 is Db in Locrian, where C natural minor has 2, D.
- b5 is Gb in Locrian, where C natural minor has 5, G.
Play C natural minor and C Locrian back to back over a Cm chord and listen for Db and Gb — those are the notes to lean on.
Chords in C Locrian
Stack the mode in thirds and each degree becomes a chord. The home chord is Cdim; the rest are the chords of Db major, since the notes are the same — what changes is which one the music rests on. There is no settled two-chord vamp for Locrian: its home chord is diminished, which is why the mode is heard as a passing colour over other harmony more often than as a key of its own.
C Locrian on the guitar neck
Because C Locrian is Db major from its 7th note, its natural fingering is position 7 of the seven three-notes-per-string shapes of Db major — the shape whose lowest note is C. Learn that shape with C as home — start and end on it, over a drone on C — and you have the mode under your fingers. Play the same shape with Db as home and you hear Db major instead. The other six positions are the fingerings for the other six modes of the same key.
How to practice C Locrian on guitar
- Loop position 7 of Db major at 60 BPM, starting and ending on C so your ear hears C as home rather than Db.
- Hold a Cdim chord (or record one) and play the shape over it. Land on Db and Gb on the strong beats — that is the sound of Locrian.
- Hear it harmonized in 3rds on the Fretboard: press Play and every note sounds with its partner while the neck lights up.
The tool draws C Locrian from its own root: the orange dots are on C and the degrees count from it. The notes are its parent key's, Db major; to hear Locrian, start and end on C.
