Students learn at different speeds; too often we can lose the fast movers as we continue to teach notes to the ones who struggle a little more.
It doesn’t have to be that way, though. We only lose those bright students because they’ve been taught through lockstep education to do what is expected and no more.
Regularly remind your students when you’re learning notes that they can be learning ahead:
If you have your notes learned you can work on memorization.
If you have the piece memorized, you can concentrate on tuning.
If you are tuning well, you can concentrate on balance, vowel matching, and timbre.
If you have all those things nailed, then you can work on harmonic analysis of the piece.
And if you have all that done, for every piece, then congratulations – you’re in the King’s Singers!
