If i had to perform in front of audience i would sing. I like singing a lot. I would feel very nervous as I'm not enough self-confident. I would be shaking. But when I saw the audience I'd calm down. I would feel their energy, and it'd help me. To perform well I would be training a lot, of cource. I would even take some extra lessons to make sure i could perform well. I would sing a bit before the audience to warm up. After performance i'd feel very happy. I'd ask my parents if i did well.I'd think about how i performed and try to find mistakes. Then I would relax and eat.
