Algerian scale
From Wikipedia, the free encyclopedia

The Algerian Scale is a scale frequently used in Algerian music. The frequent use of 1.5 steps (a minor 3rd) in the scale contributes to a sound commonly associated with Moorish music.

It is also defined as an eleven note scale with two augmented seconds. Jacques Ibert first used this definition in Escales (1924).[3]
In India's Carnatic music, this corresponds to Simhendramadhyamam.
