What color?

Phrygian with b11 and bb7: a very dark, chromatic mode, almost diminished, drawn from the double harmonic. An exotic, closed color, to reserve for moments when you seek extreme Eastern tension.

Origin & history

The third mode of the double harmonic. One of the darkest theoretical modes, mostly material for exploration.

Which chords to play it on?

Outside the functional consensus: this is an exploration color. Lay it over a vamp or a held chord to tint your improvisation with an unexpected flavor, rather than inside a cadence.

Sibling modes

The ultraphrygian scale is one of the modes of the double harmonic scale : it shares exactly the same notes as the modes below, but built on a different degree of the parent scale (double harmonic major (Byzantine)).
