Confidence is an important part of any audition. Walking into an audition with your head held high, good posture, and a big smile will go a long way to winning over the director. Wear clothes that are comfortable, appropriate for the role and that fit well. You don’t want to go in a full costume, but dress for the part. You wouldn’t wear a suit to audition for Rent or jeans to audition for How to Succeed in Business Without Really Trying. The better your look the more confident you’ll feel.
Another way to build confidence is to prepare your voice for a singing performance. Start by finding a great warm-up. Make sure you begin with breathing exercises to get air moving and loosen everything up. Just like preparing for a marathon, you need to work on your voice daily. Singing every day is the best way to keep your voice strong and healthy, so practice, practice, practice.
