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 the American "Simon and garfinkel" duet group and Terry Lin in the Taiwan Province "Youke Lilin" duet group. 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.
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 and Tu Honggang's The Passer-by of Life. 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.
