Two of my aunts sang in the choir-one a soprano, the other an alto. From as long as I can remember, until I was about 9, the two came 6 days a week to help out, as my mother was a cancer survivor, was ill often, and tired easily. They would sing is the songs from choir practice, and it was lovely! There was a Christmas Carol called, "The Christ Child" (Little White Lamb in the Manger) that was just beautiful!! I can't find it on the'net; maybe you've heard of it....
God bless you!
Scroll down to No. 13 in the mpg files. It's sung as a baritone solo - didn't see an SATB setting.
If you watch enough of those YouTube videos with the score scrolling along, you can learn to read music easily enough! When I became Catholic I had never read Gregorian notation, it is quite different from our standard "staff notation". I had to work at it a bit, but I'm pretty confident with it now.
