Suona is not a complicated instrument. Its structure is very simple, consisting of five parts: whistle, gas tag, core, rod and bowl. Eight sound holes on the wooden cone rod are staggered, seven in front and one in the back; Copper core on the pole; The core is covered with a whistle made of air cards and reeds; There is a bowl at the lower end of the rod. It is so simple, even with some simple structures, but it can play almost all the skills of wind music, and even imitate beautiful sounds such as human voices and bird songs. Taking apart several parts of the suona and playing it, we can imitate different personalities, such as being old and deep, Hua Dan's nifty and clever, Beowulf's rough and reckless ... Such a small instrument can interpret the joys and sorrows of the world alone.

Playing suona also requires some skills, and the sound hole should be completely filled with your fingers. If the sound hole is not pressed tightly, the sound will often be inaccurate. Therefore, grasping the playing atmosphere of suona has become a science. Playing suona often consumes more gas, and the higher the sound, the greater the gas consumption. Generally speaking, it is impossible to perform for a long time without intermission, but the competition between trained players, especially folk artists, is lasting endurance. "Cyclic ventilation" is the most common way to play. This kind of performance can make the breath full all the time, make the music last for a long time without interruption, and even make the whole song go in one go, which greatly satisfies the audience.

The tone of suona is rich and unique. Colorful tuning makes suona rich and comprehensive. At present, suona is divided into three types: treble, alto and bass. Commonly used high-pitched suona, there is a slight rustling in the bass area, and the pronunciation is rich; The alto tone is rich and clear, and it is good at playing various skills, which is very artistic and expressive. The high-pitched area is loud and dripping; The highest sound is sharp and harsh. If you don't grasp it well, it will become ugly noise, so it is rarely used. At present, the reformed keyboard suona has become a perfect instrument in the national band, which is more expressive.

There are many kinds of suona around the country, including big, small, thick and soft, which are usually divided into five types according to the length of the pole. The length of the small suona pole is often 22 ~ 30 cm, and its timbre is soft, which is most suitable for solo or ensemble, especially when it is played with stringed instruments such as erhu, it is tactfully undulating and more beautiful. It is distributed in Guangdong, Guangxi, Fujian, Hunan and Jiangxi provinces. Whistles used in different places are different, such as reeds, straws, and brown-purple rubber insect shells (but they are soft to blow), and their sounds are unique. Suona pole is 32 ~ 40 cm long and is popular in Jiangsu, Zhejiang and Anhui provinces. The volume is not too loud, and it is melodious when it is used to accompany songs and dances. The great suona pole is 42 ~ 57 cm long, and its voice is deep and grand, as if a hero was born, full of domineering and momentum. In Northeast China, Shanhaiguan and northern Hebei, rough suona is also the best choice for playing large-scale music. Compared with the "big pole" with a pole length of 50 cm, the cypress pole is slightly shorter and popular in Hebei, Henan and Shandong. The crisp and bright voice seems to be able to clear the clouds and make people feel comfortable. Playing minor with cypress pole, imitating the singing of China traditional drama, is particularly handy. The length of the sea flute is less than 20 cm, and the parts are also small and exquisite, but the pronunciation is sharp and loud, high and loud. The instrumental ensemble of Jiangsu, Zhejiang, Shanghai and Anhui is its best stage. There is also a special suona in western Fujian. Usually, two pieces are played together, which are called "public blowing" and "blowing". The two kinds of suona have the same structure, but the length and thickness are slightly different. Gong is short, long, thin, thick and sweet. The pronunciation of "blow" is low and rich, and it is integrated.
