What It Is

The 5th mode of harmonic minor - Phrygian with a major 3rd instead of a minor 3rd, giving it a dominant-quality triad with Phrygian's tense flat 2 and flat 6. Notes: A#, B, C##, D#, E#, F#, G#.

How It Functions

A dominant-sounding mode (major 3rd, minor 7th) built on the 5th degree of a harmonic minor key; frequently the scale played over that key's V chord.

Mood & Character

Exotic and intense - a dramatic Middle Eastern/flamenco color, tenser than plain Phrygian because its major 3rd clashes with the flat 2nd and flat 6th.
