Make an appointment for the audition as soon as possible. There may be a limited number of audition slots.
Find out specific details about audition requirements. Some production companies want the actors to bring a full resume, including a professional headshot, to the audition. The audition may require a musical number, a dance performance or acting out a scene.
Research the production company and the director. Read music reviews about the production company and director. Speak with colleagues and other performers and crew who have experience with the company.
Research the musical itself. Read about the musical and study previous performances if they are available. Pay attention to how other actors approached the role that you are auditioning for. Study the plot and the individual roles of the various characters. Study the historical and social context for the time period in which the musical is set. The more knowledgeable you are about the various details of the musical, the more prepared you will feel.
Select a song that showcases your vocal range and talent. Some production companies expect you to perform a song from the musical that you are auditioning for, but it is more common to sing a song from another production.
Practice and fine tune the song for the audition. Hire a singing coach if you are unsure of your vocal talents. Work on your dancing and acting skills as well.
Dress professionally and arrive at the audition on time. Don't wait until the morning of the audition to figure out directions to the audition location. Make sure to get a good night's sleep the night before the audition. Bring the sheet music with you for the song that you are performing. Bring a change of clothes if you have to perform a dance audition.
