On the scale mode, most Yi folk songs adopt pentatonic scale and heptatonic scale. There are two modes. One is based on [[Domsol]] three tones; The other takes [[SolDoRe]] as the backbone of the framework. In addition, the southern dialect area of Yi language also uses two scales with special structures. One is [fashion]; The other is [Solla ↓ sidoremi ↑ Fasol].
Some Yi folk songs often use different sounds to form a unique style.
Most of the Yi folk songs have boards, especially dance music such as "jumping strings", "playing songs" and "three-step strings". The rhythm of short before and long after is widely used. The "four rooms" mainly adopt scattered boards.
