"This scale is the same as Phrygian dominant except for the natural 7, which this scale has. Any time you are improvising over a chord progression that has major chords that are a half step apart, this scale (as well as the Phrygian dominant) is a good choice. The Gypsy scale is cool to use when you're going for that whole snake-charming, exotic, "magic carpet ride" sound. Blackmore captured it very well on many tunes. “Gates of Babylon” by the Ronnie James Dio-fronted Rainbow is a good example."
