In music, the Phrygian dominant scale is the fifth mode of the harmonic minor scale, the fifth being the dominant.[1] Also called the altered Phrygian scale, dominant flat 2 flat 6 (in jazz), or Freygish scale (also spelled Fraigish[2]). It resembles the Phrygian mode but with a major third, rather than a minor third.
In the Berklee method, it is known as the Mixolydian ♭9 ♭13 chord scale, a Mixolydian scale with a lowered 9th (2nd) and lowered 13th (6th), used in secondary dominant chord scales for V7/III and V7/VI.
