I know the arguments in favour of giving people recordings of the music they need to learn to sing their part in a choral group. It’s a very common practice in the barbershop world, and an increasingly common one in classical choirs. And it’s true that it enables people who don’t read music to participate with very little effort, and indeed to perform much more complex music than they would be able to without it.
And, yes, having people participate in singing is a Good Thing. No argument there.
But still, I do think that every so often someone needs to point out the problems that learning tracks create as well as their opportunities.
