This music family is also called the Persian-Arabic music family. Its region mainly includes parts of West Asia, North Africa and Central Asia, which is roughly equivalent to the so-called Islamic world. The main people who adopt this music system in China are the Uighurs, Tajiks and Uzbeks.

The West Asian and North African music system has the following characteristics in terms of musical form:

The fixation of the music and the melody. The music progression of this music system has both a fixed aspect and a large number of Use musical sounds with accents. However, this kind of accented music is different from the tone of East Asian music. It is based on the twenty-fourth equal scale of traditional Persian and Arabic music. Specifically, in the sounds that make up the middle second (34 whole tones) and the augmented second (64 whole tones), there will be a minor second interval that moves up and down, causing "acoustic" sounds. Therefore, this kind of cavity can be regarded as a conditional cavity. Conditional accented music is exactly the charm of the music of West Asia and North Africa.
