Look at the mouth shape: this is hard for ordinary people to see. To keep pace with the mouth shape of his (her) lyrics, you almost have to know lips. But it's much easier when you close the door. Real singing makes facial muscles a little nervous, while lip-synching makes muscles relax.

Slow song recognition: Generally, the live reverberation is relatively large, and the singing sounds relatively wide, but the lip-synching is not so wide. You have to listen to MP3 before you can hear this method.

Fast song recognition: If a singer chooses to lip-synch a fast song, it is almost like saying that he is lip-synching. Breathing, intonation, easy to show.

Treble recognition: treble is usually called a person's vital capacity, and a person is singing a treble and dancing, so there is no need to lip-synch, which is simply a god of songs.

You can choose a song suitable for the bride to sing to express your love for the groom, but generally single brides rarely sing it. There are actually many brides who can't sing. You don't have to sing with the real thing, you can lip-synch. Most of our weddings are like this.

Or both sides sing together, but generally speaking, this is mainly for newcomers who both sing well or like singing, which will be very romantic.

In fact, you don't have to sing at the wedding. You can set some other plots, but you can also use background music. As for the plot, you need your own creativity and imagination. If you want to play singing, I suggest you lip-synch and let the groom lip-synch.
