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.

Taking the suona commonly used in the Yi area as an example, the suonas used by the Yi suona masters are almost all made of wood, and the suona poles are mainly made of lacquer trees. Straight tender sumac should be selected in winter. In the words of the common people, the time should be set after the tree is launched (after autumn) and before it is flooded (before spring). Only the wood selected during this time is not easy to crack and deform. . After the selected tender sumac has been cut home, place it in a ventilated and dry place and allow it to dry slowly. Then take it out to remove the bark, use a knife or other sharp tool to shave it smooth, the specific requirements are that the whole stick should be round, the upper part should be slightly thinner, and the lower part should be slightly thicker. Specifications and sizes are cut into semi-finished products. At this time, drilling can be done. Drill the ventilation holes first, and the ventilation holes should be drilled from bottom to top. Since there are no modern drilling tools, folks have always relied on iron drills made by blacksmiths to drill holes. After the middle is red, take out the part that is not red and not hot at the back with your hands, and align the drill with the center of the cross section of the lower end of the suona rod and scorch it hard.

The ventilation holes should be large at the bottom and small at the top, and the whole hole should be round and smooth. After the vent holes are made, the sound holes are drilled. The sound hole of the suona rod is 7 on the front and 1 on the back. The sound hole on the front is generally (take the small suona of the trumpet suona as an example) about two fingers from the upper side and 4 fingers from the bottom side to set the hole point, and then use the same hole distance to drill and drill one by one. It is still an earthen iron drill, and each sound hole should be generally large. If all the sound holes are different in size, then this suona rod will be scrapped. The sound hole on the back should be drilled in the center of the first and second holes above the sound hole on the front. The size of the hole should be the same as the hole on the front, neither big nor small. In this way, the suona rod is successfully made.

The role of the suona rod is the most important in the suona part. In particular, the suona score should be reflected by the closing change of the sound hole on the suona rod. There is no such closed change of the sound hole on the suona rod. Then, after the sound of the whistle passes through a series of sound transmission holes, although the sound is enlarged, it is still the original sound, without the rise and fall, without cadence, and even less. What's the score. Therefore, there is no suona without the suona rod.
