During the abcd Initial Conducting Course I led earlier this year, I had several conversations with conductors about how to manage rehearsal planning in the particular circumstance that you don’t yet know the much about the choir you’re planning for. How do you work out what will be appropriate repertoire when you don’t yet know the skills and experience of the singers you will be working with?
This is a circumstance that can affect anyone who is lined up with a conducting job they’ve not yet started, but it is felt most strongly in early career musicians who don’t yet have a fund of previous similar experiences to draw on.
So, the first thing is to do what profiling you can. For those moving to new teaching jobs, the age of the children you will be working with gives you quite a lot of information about what to expect, and you can also glean a good deal from what kind of repertoire your predecessor was using with them. If they have any recordings of recent performances, this will also tell you a lot.
