There really is nothing more therapeutic than a great rehearsal.
Tonight was the "rehearsal-before-the-dress-rehearsal" rehearsal for my chamber choir, but it had all the feeling of a dress rehearsal. The music is in great shape, soloists are all healthy (knocking on wood right now), and there is a general feeling throughout the choir that we are well prepared. It actually makes me a touch nervous. I'm hoping we haven't peaked in some of the repertoire.
Hopefully something will go wrong in the actual dress rehearsal so that the singers will still be "on edge" for the concert on Saturday - however, if everything goes well on Thursday, then I'll be OK with that too.
