Mode reference
Locrian mode
The minor scale with a flattened second and a flattened fifth · C Locrian = C – D♭ – E♭ – F – G♭ – A♭ – B♭
Locrian is the seventh mode of the major scale, which means C Locrian uses the notes of D♭ major but treats C as home. Every mode on this page keeps that relationship: the same step pattern, started somewhere new.
The flattened fifth means the tonic triad is diminished, so there is no stable home chord. Almost never used as a key centre; it turns up as a passing sound over a half-diminished chord.

Locrian on every root
Each row is the same step pattern started somewhere new. The last column is the major scale that contains the same notes — useful when you want to find the mode by thinking in a key you already know.

Hearing it rather than spelling it
A mode is only a mode while the music keeps treating its tonic as home. Played over a D♭ bass, C Locrian is just D♭ major. Played over a C drone, the alterations become unmistakable. That is why modal writing tends to stay on one chord for a long time.
