American vocal educator? William wennard? It is described like this:
With the relaxation of vocal cord muscles, arytenoid cartilage may exert great longitudinal tension on the ligament at the edge of vocal cord. This tension allows the speaker to further improve the pitch after the vocal cords are stretched to the limit. At this time, the vocal cords become very thin, so there is almost no vertical phase difference. The vocal cord muscles will fall to both sides of the throat, so that the vibration only occurs on the ligaments.
The falsetto obviously has breathing sound, which is often considered to be similar to the flute with few overtones. Compared with the normal vocal mode, speaking and singing in falsetto is obviously more restricted in timbre, sound quality and volume. In the past, because women's falsetto changes are not as obvious as men's, it is often considered that falsetto is a unique way of vocalization for men. In fact, both men and women will falsetto.
Usually, most people can only make falsetto occasionally, but men who change their voices in adolescence are particularly prone to falsetto.
affect
Most pop singers (both men and women) sing with real voices in order to obtain a natural, intimate and close-to-oral style. Some female singers (such as Chyi Yu and Huang Yingying) mainly sing falsetto when singing songs with wide range and strong artistry.
Male singers often use falsetto when singing backup voices, such as garfinkel in Simon & garfinkel and Terry Lin in Taiwan Province's "Youke Lilin" duet.
This is also an important feature of country music style duet. But there are not many male singers who sing in a soft falsetto like the lead singer in Modern Talking.

trait
The key to producing beautiful falsetto is to have a relatively high vocal position. When using falsetto, we should pay attention to the smooth transition between true and false falsetto, and there should be no interruption. Generally speaking, falsetto is weak, but it can also be converted into half-true, half-false, half-dumb and half-dumb calls when necessary. Many heavy metal rock singers like to sing with hoarse falsetto.
False voice can also be used as a way to modify the sound. The "mixed sound" of the combination of true and false sounds can produce a soft, delicate and slightly ethereal artistic effect. Compare Tong Ange's The Passer-by of Life with Tu Honggang's. The former sings with pure true voice, while the latter sings with timbre between true and false voice. Liu Huan and Chyi Chin's Winter are also different in this way.
