When did you start singing?
In fifth grade, when I joined the Michigan State University Children's Choir. And then?
I sang at Emory University and Harvard Business School.
And now? I sing with the New York Choral Society, a volunteer chorus. Concerts are at Carnegie Hall and Lincoln Center.
The audition? It was intimidating! I sang Mendelssohn's Elijah; Puccini's Messa di Gloria; and read passages in French, Italian, German, and Latin. How big is the choir? Two hundred people — a lot of them are lifers.
Practice? One evening per week for three hours, and one Saturday a month for six hours.
Favorite karaoke song? Carrie Underwood's "Crazy Dreams."
Advice to beginners? Join a church choir, even if you aren't religious. — Jessica Flint
