What is a college SATB choir?
What an awesome experience.
4 part mixed choir....soprano, alto, tenor and bass.
NOW... if I'd have said SSAA, that would mean Soprano I, Soprano II, Alto I, Alto II, or SSA which would be Sop I, Sop II, Alto. I also sang in the Womens Glee Club as well, which was voiced like that (either 3- or 4-part womens voices in the music).
I usually sang either Sop II or Alto I, but I've also sung Sop I. Alto II is just too low for me - not a natural part for my range.
