The title of this post is the subject line of an email I received recently from a friend who is grappling with the question of how to inveigle visitors to/potential members of her chorus to return and become actual members. This is a question that all choirs face, but it is exacerbated in this case because it is a group whose members are spread over a wide geographical distance, and who only meet once a month. So the opportunities for people to 'go off the boil' (as my correspondent put it) are significantly higher than for those choirs that meet weekly.
What they do so far is to 'pamper while they are at rehearsal, follow up once or twice between rehearsal (designated officer does this).' What they don't do is issue any music or learning materials until people are paid-up members, and the email implied that not being able to practise was a significant obstacle to ignition.
There are thus two distinct but related issues lurking in here: how to keep people's enthusiasm between rehearsals, and the pragmatics of giving out chorus property.
