Every musician has to make this decision when they start a new piece of repertoire: in what order should I learn this? But it always feels like it matters more when you’re a making the decision on behalf of an entire ensemble: what approach will help the performers learn grasp it with most efficiency, security and confidence?
If you make a poor choice of strategy in your private practice, it’s only your own time and emotional energy you’re wasting. If you take a sub-optimal course of action leading an ensemble, not only are the wasted person-hours multiplied up, but you may create obstacles to your musicians ever really bonding with the piece. (No pressure.)
