What are the characteristics of Miao music in mode scale?

In terms of modal scales, Miao folk songs mainly adopt four-tone series and five-tone scales. The main frame of the pattern has two three-dimensional structures: [[Domsol]] and [[Radomie]]. Introducing business sounds into the first frame to form a [[DoReMiSol]] Gongdiao four-tone series, and the range of such works does not exceed five degrees; Extending this frame (using tone sandhi) and introducing feather tones, two fine tuning tone sequences [[SolLaDoMiSolDo]] and [[SolLaDoMiSolLa]] are formed. At this time, the angle sound is often unstable, with upward sliding and downward sliding cavities, especially the rotation method between the size of the palace sound formed by downward sliding has the most national characteristics, and even becomes the symbolic acoustic characteristics of national traditional music. The second mode frame mostly forms a pentatonic scale.
