Tip one: "Be unique and original"
Remember there'll be heaps of other girls auditioning, so your performance has to stand out, whether it's a cool outfit or a different way of presenting your performance.
Tip two: "Record your performance so you can work on it."
Listening back to yourself singing is a great way to see what areas you need to work on improving.
Tip three: "Have fun! Entertainment should always be fun."
If you look bored or anxious when you're singing, your audience will feel the same way, so just relax and be yourself and don't be afraid to let your personality shine!
