Telemann, "Laudate Jehovam" . We sing this one for Easter.
The Telemann sounds a lot more modern - the big difference is that instead of separate vocal lines of equal importance in each part (a Renaissance thing) the melody tends to stay in the soprano or tenor, with the other parts supporting the single melody.
My better half is a big fan of Bach. He is from that period.
I imagine Bach was played at Christmas time too.
My high school choir sang a lot of Bach. Not any more. Too religious. Times have changed!
