Mongolians have an ancient vocal method. What's the name of a person singing multiple voices?

Humai, also known as "Lin Hao Chaoer", is a superb singing form of Mongolian polyphony Chaoer and an art of "throat". With special vocal skills, one person can sing two voices at the same time, forming a rare multi-voice form. Singers use breath-holding skills to make the breath violently impact the vocal cords, making a strong bubble sound and forming a bass. On this basis, skillfully adjust the oral * * * sound, strengthen and concentrate overtones, and sing transparent and clear high notes with metal sounds, thus obtaining extremely wonderful sound effects.

Mongolians have a strange saying about the appearance of Humai: When ancient ancestors were active in the deep mountains, they saw the tributaries of rivers bifurcate, waterfalls fall, and folk songs echo with valleys for dozens of miles, which made people move and hear, so they imitated and produced Humai. Humai is still circulating among the Mongolians in Altai mountain area of Xinjiang. Humai's repertoire is not particularly rich because of the limitation of special singing skills. Generally speaking, there are three kinds: one is to sing beautiful natural scenery, such as Ode to Altai Mountain and Ebu River; The second is to express and simulate the lovely images of wild animals, such as "cuckoo" and "black bear", and retain the musical remains of the pig hunting period in the mountains; The third is to praise the good horse grassland, such as the "four-year-old hippocampus". As far as its musical style is concerned, Humai is mainly short-tune music, but also sings some short-tune songs, and there are not many such tracks. Judging from the Humai legend and the theme of the track, the singing form of "throat sound" is the product of the hunting culture period in Mongolian mountainous areas.
