C Locrian dom Scale
C Locrian dom contains 7 notes: C, D♭, E, F, G♭, A♭, B♭. It has 4 flats: D♭, G♭, A♭, B♭. The step pattern is H–W+H–H–H–W–W–W.
A dark dominant mode where the major 3rd clashes dramatically with the b2 and b5. It functions as a dominant scale for V chords resolving to dark, Neapolitan-colored tonics.
The formula is 1, b2, 3, 4, b5, b6, b7. The major 3rd provides dominant clarity, the b2 adds Phrygian darkness, and the b5 adds instability. In jazz, it's used for altered dominant chords in minor progressions.
The tension between the bright 3rd and the dark b2/b5 makes for dramatic phrasing. Use the b2-to-3 augmented 2nd slide for instant exotic color. Best applied over V7 chords resolving to dark minor tonics where standard Phrygian dominant isn't dark enough.
