Michael....I know this is not this year...but I don't think it has changed much and have had a client audition there already this year, but my D auditioned there two years ago. The dance auditions were first, if I recall. (sometime you might want to search the forum from this time of year the past 2-3 years when people posted accounts of auditions, just an idea). There was time to change into dance clothes. There was NO introduction to the program for students and parents and no current students taking questions or any of that which many other programs include. The dance audition was the weakest by far of any school my D auditioned at. I recall her saying that anyone could do it who had never taken dance in their life (she is a lifelong dancer, however). Sure, a dancer might shine more in their presentation and how they moved but anyone could do the steps as it was very very basic. I even think they went down the line and asked each kid why they wanted to go to Emerson in front of everyone else. Better think of something different to say!
I don't recall a vocal warm up. Changing clothes is given anywhere we have been. The voice audition is with one person and the acting one is with another. Yes, they can work with you. I know they had my D sing one of her songs a different way. She also redid one of her monologues a different way as directed. They were nice. However, my D felt the audition space was very small. She said it was awkward to perform a song or monologue in such a small space compared to anywhere else. She didn't do additional pieces but did hers different ways.
For parents, while I had a great time in the waiting room meeting up with CCers for a few hours, I thought it wasn't so great to not do any presentation or greeting to those who had traveled so far. They surely did nothing to tell about the program or anything. There surely were no refreshments, lol. It was interesting to see how differently each school went about the audition day. I don't judge programs on this but am merely commenting. The important thing is to like the program, not so much the audition day! Luckily we had already visited this school and my D had done an overnight with a friend in the program as well or otherwise, we'd have come away learning very little about it from the audition day.
