What makes F♭ 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 F♭, F♭ Locrian has C𝄫 where F♭ Phrygian has C♭; every other note is shared with F♭ Phrygian (F♭ G𝄫 A𝄫 B𝄫 C♭ D𝄫 E𝄫).
