There are pieces we rehearse that make me almost comically petulant.
This tempo’s too slow.
These words are too complicated.
That chord is icky.
Clearly, someone needs a nap.
But it’s like that. Some music is just so darn full of charm (however you define it), you can see pretty clearly that singing it is going to be a delight (however you define that). Other pieces are stubborn, bumpy, slightly ill-mannered, protective and don’t give themselves up easily. And I’ve learned that loving them precisely because they’re stubborn, bumpy, slightly ill-mannered, etc. brings about actual appreciation for the depth, the complexity, the subtleties that reveal themselves only after some hard work.
The charming songs are by definition delightful, but the challenging ones – big rewards to be had there.
