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 suona is mainly made of barley straw. When the barley is about to head in April and May every year, look for two or three clumps of wheat seedlings that are growing better. After uprooting and bringing them home, they are placed under the eaves in front of and behind the house to dry in the shade, and then received at home. , each plant can only use one middle section at most two sections, the two ends of each section must be removed, and only the middle part about 3 inches long can be used. The barley orange peel should not be thick or thin, if it is not smooth, not soft, and the color is white but black or has black spots, it should not be used. After selecting, use scissors to cut each section about 0.5 cm long, and then put them in a small box, so that they can be used as a whistle at any time. When using it, put the whistle in your mouth to moisten it, then bite it gently with your teeth, then put it on the duck feather tube and make a looper with a thin thread to tie it in the middle of the joint between the whistle and the duck feather tube. Position, moderate tightness. Every part of the suona is important, but the whistle plays a particularly prominent role.

The whistle is not good or the whistle is broken, it will affect the effect of blowing or blowing. The whistle mainly plays the role of pronunciation. When the airflow in the mouth is forced through the flat whistle, the whistle will make a sound, which is equivalent to the vocal cords in the vocal organ when people pronounce. For example, if a person's voice is high-pitched and thick, it means that the vocal cords are thick and long, and if a person's voice is sharp, it means that the vocal cords are thin and short. In the same way, the thicker and longer-cut whistle blows a thick and deep sound, while the thinner and shorter-cut whistle blows a sharper sound. Therefore, according to the size of the suona, how to choose the whistle becomes the key to playing the suona.
