Learn your voice, vocal range and style. You should know what vocal parts you can sing, what your note range is and what singers you sound like. This will help you choose songs that best show off your voice and prevent you from signing up to audition for parts for which you are not suited.
Make a demo reel. Compile clips of your singing into video and audio files you can send to producers who are considering you for an audition so they can see if you are the type of singer for whom they are looking. Make sure the quality is good and your voice can clearly be heard above any music or background noise.
Take headshots. Many producers are looking for certain looks as well as certain voices for their projects. Work with a professional headshot photographer to take a variety of photos that capture your look and essence.
Visit audition sites online. Many websites are dedicated to compiling auditions, including craigslist.org, laauditions.com, auditionssinging.com and backstage.com.
You can also use Google and enter phrases like "vocal auditions" and "auditions for singers" to find additional audition opportunities.
Network with people in the music industry. Attend concerts, visit music venues and speak with other vocal artists as much as you can. With so many people competing for a relatively few number of singing opportunities, personal relationships can be great ways to get the inside scoop on auditions and to learn about gigs that may not be listed online.
Submit the required material to producers. When you find a listing or learn about an audition opportunity, send your reel and/or headshot if requested to the people running the audition. Be sure to give them exactly what they are looking for. If you do not give enough information or submit the wrong type of reel, you may not be invited to audition at all.
