I just did my first audition in North Carolina. All I had to do was sing 16 bars. I chose "Ladies in Their Sensitivities" from Sweeney Todd, which is right out at the edge of my abilities. I knew I could do an easier song and do pretty well, but I figured that I should demonstrate that I could handle a challenge.
So how did I do?
I dunno. They cut me off in the middle of the song, perhaps because I was bad in some way I wasn't aware of, perhaps because my song is so slow and they wanted to keep things moving. When I perform I find I usually can't usefully evaluate my performance, but I think I did a pretty good version of the song. I'm just not sure whether the impression I made was "Aaron nailed this tricky song" or "Aaron's making measurable progress with this tricky song."
OTOH I was the only man auditioning, but that's not much assurance that I'll get cast. Directors always have little black books full of tried and true local performers...
