This is your opportunity to learn about the vision or style the director has in mind for the production. Be prepared to change you idea of what a character is. Listen to the director. There are no small parts, only small-minded actors. Actors should realize that all experience on-stage is valuable.
Excellent productions have excellent performers in all roles.
Be aware that the director casts for the good of the production if the theatre company is dedicated to quality theatre. Learn to react to other actors on-stage. Each actor's contribution adds to the chemistry being created by the group. Take time to find a song for auditioning that reflects the style of the show or the feelings you may have discovered in a certain character. We prefer that audition songs not be from the show you are auditioning for.
