As the above question reads, how does one sing barbershop? I'm hoping to get into Ladies First, our school's barbershop choir.

I also start planning to drink tea, come April, to ready my voice, instead of drinking soda, etc.
Yep.
And the one girl I actually feel semi-comfortable asking won't help. x.x

Also, yes, i'm aware I won't have a life come September, should I get in, but i'm ready for that!
