Yay, that was fun. :) I sang half of one song and all of another, and then he worked with my voice a bit. He said he'd want to bring me on as a soprano but he doesn't have room for sopranos so if he did it'd be a first alto spot, which is OK with me as I'd like to be able to work on my lower range again. And I could always be bumped up if there's ever an opening "higher up." He gave me very nice compliments, though, which was kind of surprising - I figured he'd be disappointed since I'm definitely not up to par with most of the vocal performance majors that go to OSU. But he said he thought I'd make a very good choir teacher (I don't know how one can tell by listening whether one would make a good teacher, but that's OK!)
And now I wait for a few days to see if he liked me enough to put me in his choir!
