Explain in detail the suona in instrumental music?

Suona was called Zoho, Zonai and Surnai in ancient times. Originally a Persian musical instrument, it was introduced to China before the Ming Dynasty, initially as a military entertainment and later as a folk musical instrument.

Suona is composed of two reed whistles (made of spring), a core (copper), a rod (wooden cone, ***8 sound holes, front 7 and back 1) and a copper bowl (small), which is blown vertically with different specifications. At present, the commonly used drum sound is the high-pitched suona in D key. The range is a'-b3.

Suona has a loud and rough voice, and is good at expressing passionate scenes and stimulating cheerful interests. It is often used in folk festivals, weddings, funerals and opera scenes, and is often used in combination with percussion. Generally speaking, the performance styles are divided into two factions: North and South. Southern factions are mostly used to perform or accompany national dramas. It is widely spread in the north, and the playing skills are also very complicated.
