2, just sing by yourself, don't care too much about the action, because it will affect the quality of singing.
3. See what difficulty song you are singing. If it is easier to sing, then you can walk around the stage and sing to the audience. If it's difficult, it doesn't matter to stand and sing. Others will marvel at your difficulties.
It depends on your original popularity. If your popularity is already high, you can wave your arms to the rhythm, but if your popularity is not high, don't do it, you will be laughed at.
5. It's better to have friends under the stage. They can give you some screams and flowers at halftime! Everything is fine! 6, once again, you can't be too stiff and natural, so others will be natural, otherwise you will be more distorted! ~
