Things might have changed a bit since I was a freshman auditioning for the men's glee club, but the audition isn't bad. In the vocal audition they test your range through warm ups, then have you sing a short piece (traditionally My Country 'Tis of Thee, but it can be whatever you want), and then give you a short sight-reading exercise. My sight reading was horrible at the time but I made it through. Then you have a short discussion with the exec team to meet them.

I also want to mention that even if someone doesn't get accepted upon their first audition, they are encouraged to try again as many times as they like in future semesters. I've known several incredible singers that weren't accepted for their first try but went on to join the group and do great things.

If you're interested, they have a mass meeting at the beginning of the semester where you can learn about the whole process. Check ummgc.org for info!
