What makes B♭ Phrygian different
Phrygian is a minor mode whose second degree sits only a half step above the tonic, and that flat second is all that separates it from natural minor. The half step from ♭2 down to 1 gives the mode its Spanish and metal colour, and the major chord on ♭II, a half step above the tonic, is its signature cadence. It's the third mode of the major scale, so it shares its notes with the major scale a major third below its root. Its v chord is diminished, so it can't cadence the way a minor key usually does. On B♭, B♭ Phrygian has C♭ where B♭ Natural Minor has C; every other note is shared with B♭ Natural Minor (B♭ C D♭ E♭ F G♭ A♭).
