What makes me feel relaxed? Just having fun, and not caring what other people think! If you have fun and joy singing, the audience will enjoy it too, no matter what! To feel relaxed, I always think about a good outcome of what I'm doing and what I could do after, like things I enjoy. I also think of Syaoran in my head to make me feel relaxed, it puts a dreamy look on my face. Don't sweat it! I know singing is kind of nerve-wracking, but don't worry about it! Just have fun, and look at the person in the audience that makes you feel happy, confident, encouraged, etc. Don't forget to smile, and try to have some energy! If you look happy (you don't necessarily have to be), then the audience will like your performance! I know you'll do well!
