Joining an A Cappella?

<p>Hey guys~
One thing I've always wanted to do since I got into musical theatre was to join an A Cappella in college. I know there are several very talented A Cappella groups at JHU, but how easy is it to audition for one? During admitted students day, I really enjoyed the JHU Octopodes and when I looked at the website at home I got to sample some of their music...it was quality. Anyways, is it relatively easy to join an A Cappella such as the Octopodes and go about competing with other collegiate groups? I discovered this year that I have a strong bass voice but unfortunately, I've never taken any private voice lessons... Thanks for the help!</p>
