Tonight the Genuine Brass Quintet (with Dave, Megan, Aaron, Caitlin and myself) played for Dave's master's degree recital. We performed Ewald's Quintet No.2, and we played it very well.
The reason I mention this, is because we had performed the exact same piece in its entirety on Friday for some high school students, and I think the quintet would agree when I say that it did not go well at all. From faulty music stands to individual mistakes (I personally had many) and an overall lack of group focus.
With no rehearsal since that very average performance, we came out this evening and played Ewald 2 with vigor, musicality and polish.
I've racking my brain to figure out how there can be such a huge difference in a group over such a short period of time.
Of course there are personal stressors, such as school or personal issues, that can contribute to a less than stellar performance. What are some other reasons that you can think of?
