Scales of the World
The Rhaoui scale comes to us from the Middle East.
I surmise that it is also used in the music of the far east as I have seen the same scale being called “oriental”.
This is a scale that is much like the Locrian mode, the difference being that the Locrian has a flat third and the Rhaoui a natural third.
This scale has a restless wondering quality which is suggestive and relaxing.
Listen to and use these scales with an open mind if you are not from the Middle Eastern musical cultures.
