You are constantly having to cover the basic ground for new members, which leaves less time for building on them to develop advanced skills. And a piece you worked up to a good performance standard just a few months ago loses its polish much faster if 25% of the chorus who did that work have been replaced.
At the same time, though, there are commensurate advantages. People learn at the fastest rate when they first join a choir, so having a constant new influx keeps the pace up and stops people getting into too much of a rut. And newcomers slot in at a group’s current level. They look around them to see what other people are doing and join in. So the loss of skills from people leaving is to an extent balanced by a dynamic in which it is easier to effect change.
I think the “looking around” factor, the atmosphere of the group, is the most important. I have had a lot of new singers in the last year or so in my community group, and the new singers have a strong herd instinct. If all the continuing singers whip out their pencils to write down every little marking I give them, the new people will quickly adapt to that behavior also. If I’m working with the altos, and the other sections listen closely so they can apply whatever I’m telling the altos to their own part and are ready to start at the same measure when I say “tutti”, so will the newcomers.
Conversely, I’ve had to start over again teaching them five-vowel Latin. Haven’t had to hear so much “cray-doh” in years.
