I usually sing oratorios. Why do you feel that you can't hear your own voice and can't control it when you arrive at ktv?

Capella and KTV are different in singing.

In cappella, the voice is usually very tight, but in KTV, if you want to sing well, you have to let go of your voice (not shout ...). Also, you'd better not choose that kind of lyric song. Singing this kind of song in KTV is very tiring, and it is estimated that my voice will be ruined after a few songs. It is suggested to find some light music, be bold, sing at the top of your voice, and it will be OK.

It should be no problem to go to KTV more often.

Well, also, if you really feel that you can't hear your voice at first, you can ask to turn down the accompaniment before singing.
