Db Locrian Mode
Db–D–Fb–Gb–G–A–Cb · root also written C#
Db Locrian is the 7th mode of the D major scale: Db–D–Fb–Gb–G–A–Cb. Its character: unstable, dissonant, and eerie — the darkest of all modes.
The flat 2nd and flat 5th create a diminished root chord, making the tonic feel inherently unresolved. Used sparingly for maximum tension and unease. On guitar, target the flat 5th (G) in your phrases — landing on it against the root is what makes a line sound Locrian instead of plain minor.
Because every mode of D major shares the same seven notes, any D major fretboard shape works for Db Locrian — what changes is the note you resolve to. Loop a Db° vamp or a backing track that stays on Db, keep resolving your phrases to Db, and the Locrian color comes through. You'll hear this sound in metal and jazz.
Db Locrian is mode 7 of D Major — same seven notes, resolved to Db instead.

Chords in Db Locrian
The seven chords of D Major, reordered to start from Db — vamping between the first two or three keeps the Locrian sound from collapsing back into the parent key.
Songs That Use the Locrian Sound
Black Sabbath — “Black Sabbath”
The tritone (flat 5th) that opens the song captures Locrian's essence. Tony Iommi leans into the diminished quality for maximum dread.
Dream Theater — “The Glass Prison”
Uses Locrian passages in the heavy sections, leveraging the diminished root chord and flat 5th for intense, unsettled riffing.
John Coltrane — “Impressions (bridge)”
While primarily Dorian, Coltrane explores Locrian territory in his improvisations over half-diminished chords, pushing into its dissonant character.
Db Locrian Mode FAQ
What is the Db Locrian mode?
Db Locrian is the 7th mode of the D major scale — the same seven notes starting from Db: Db–D–Fb–Gb–G–A–Cb. The interval formula is R–♭2–♭3–4–♭5–♭6–♭7.
What is the difference between Db Locrian and Db natural minor?
Two notes: where Db natural minor has 2, Db Locrian has ♭2 (D), and where Db natural minor has 5, Db Locrian has ♭5 (G). Those alterations are the entire difference in sound — everything else about the two scales is identical.
What chords work with Db Locrian?
The seven chords of the parent D major scale, reordered to start from Db: Db° (i°), D (♭II), Em (♭iii), F#m (iv), G (♭V), A (♭VI), Bm (♭vii). A two-chord vamp between Db° and D is the classic way to establish the Locrian sound without drifting back to the parent key.
What major scale has the same notes as Db Locrian?
D major. Db Locrian uses exactly the notes of D major starting from its 7th degree, so every D major shape on the fretboard doubles as a Db Locrian shape. The same notes also spell D Ionian, E Dorian, F# Phrygian, G Lydian, A Mixolydian, and B Aeolian.
How do I practice the Db Locrian mode?
Modes live and die by harmonic context — run over a static Db° vamp or a drone on Db, not a full progression that pulls back to the parent key. Play the D major shapes you already know, resolve every phrase to Db, and lean on the flat 5th (G). OpenFret's free Studio has a fretboard viewer and metronome for exactly this, and Guitar Quest turns scale practice into a game with real-time pitch detection.
