Music requires percolation time to achieve the best results.
Think about the number of pieces a high school, college, or community choir might perform only once before putting away. It’s a significant percentage, and that’s too bad, because the percolation works better in performance than in rehearsal.
Every performance you give of a piece helps the ensemble to learn what works and what doesn’t. It helps them to overcome mistakes, to anticipate, and to hone a performance into something really special.
Trust the percolation time, give multiple opportunities to perform, and watch as ensembles reach ever higher in their musicality and sense of ensemble.
