Yi nationality suona, Yi nationality double-reed air-sounding musical instrument. In Yi language, they are called Mohe, Mohong, Bailai, Zenai, etc. Because the whole body is made of wood, it is also known as the Yi wooden suona. The shape is more simple and bigger than the ordinary copper bowl suona. It consists of a reed whistle, a core, a tube body and a horn.

The whistle of the Yi suona is generally called duck feather tube. The reason why it is called duck feather tube is because the whistle tube is selected from the hardest, thick and smooth feather shaft on duck wings. The reason why it is selected is because its quality is better than chicken feathers. The holes are unobstructed, smooth and well ventilated. It is required that the top and bottom are the same thickness, and the length is about 1 inch. The general suona craftsman must have spare duck feather tubes, ranging from 1 or 2 to 3 or 5. The lower part of the duck feather tube should be inserted into the upper hole of the small tube, and the upper part should be covered with a whistle. The thickness of the duck feather tube is generally suitable for the upper hole of the small tube. If it is thick, it cannot be inserted. If it is thin, it will loosen and shake. It is inconvenient and affects the playing effect.

The whistle of the suona mainly plays the role of a microphone. It transmits the sound from the whistle to the small tube, the large tube and even the suona rod through itself. The whistle serves as the medium of sound in the parts of the suona, especially the role in the progression of the sound transmission hole from small to earth, which is particularly important.
