The music we are more exposed to, whether it is European and American classical music or contemporary pop music, is based on the twelve-average law, and the smallest scale difference is half a key.
However, the music system in the Middle East has experienced the evolution from nine laws to seventeen laws and then to twenty-four laws, with different music theories. What's more noteworthy is that there are widely differences, that is, quarter tones, in Middle Eastern music.
So, how can a person who claims that "any style of music can be played on the piano, and instruments with 12 average rhythms are very expressive" achieve a scale of "one quarter down" on the piano? The answer, of course, is no play.
The scale form in the Middle East music system first appeared on the basis of traditional local instruments, and later evolved into the scale in our present sense, which is why the melody of Middle East music can only be played by traditional local instruments in most cases.
Hope to adopt! thank you
