cathedral chorister - Domchorsängerin

So far I've only watched the performances of the Bremen Cathedral Choir cause I'm a new member. But tomorrow I'll sing along in the worship / service. We'll sing a cantata by Johann Seb. Bach. It's the first time that I have a performance in a cathedral with a choir, therefore I'm very curious about how the acoustic will be! Of course I'm very nervous cause it's my first performance with this choir! This evening we have our last rehearsal before appearance tomorrow at 9 o'clock (german time).
