Tuning in for choir practice

It's time again for my choir practice and I usually look forward to it as singing always gives you energy. Breathing in the right way and trying to produce a sound as nice as possible is so inspiring...But today...I'd rather stay at home as I can't stand one of the monotonous pieces we will perform in two weeks...It's a piece that was found in an archive and I really think that it should have stayed there...Maybe it sounds nice when we all sing together but I can't catch the pulse of the stuff...It feels like eating a lot of crispbreads without drinking anything between...And as my mental state is this the singing will certainly sound flat and stiff and dull...A good metaphor for anything that we're forced to do...It becomes tuneless and without rhythm. But then again there are these wonderful songs that make every cell membrane come alive, breathing becomes easy and your stiff face muscles loosen up...
