Musical Challenge

This piece of music annoys me so fits with mono Monday! I don't particularly like it, it's in German which I always find tricky, it's written for a quartet so really designed for soloists, the score is put together strangely and hard to navigate and each voice spends a lot of time not singing because it was written for a quartet of soloists who, being soloists, don't often sing at the same time. I would rather not be singing it but I will have to do so. It annoys me.
