What makes C♭ Locrian different

Locrian is the only mode of the major scale with a diminished fifth, so its tonic chord is a diminished triad rather than a major or minor one. That flat fifth is the one note separating it from Phrygian. Without a perfect fifth the tonic never sounds at rest, which is why whole pieces in Locrian are rare and the mode lives mostly in theory, over half-diminished chords in jazz, and in metal riffs. It's the seventh mode of the major scale, so it shares its notes with the major scale a half step above its root. On C♭, C♭ Locrian has G𝄫 where C♭ Phrygian has G♭; every other note is shared with C♭ Phrygian (C♭ D𝄫 E𝄫 F♭ G♭ A𝄫 B𝄫).
