As an addendum to my post from last week on Lemov’s principle that 100% compliance with instruction is fundamental to the achievements of a class (and by extension, in our context, a choir), I thought it worth going into a little more detail about some of the guidance he gives for how to achieve this. It does sound scarily draconian on first acquaintance, but the point of it is to make the culture of compliance invisible so that everyone just gets on with things without having to stop and belly-ache about it.
His first point is that we should always use the least invasive form of intervention. If you can get someone back on task using just eye contact, that’s all you should use. A reminder to the group as a whole can be a way to reinforce the universality of expectations while bringing attention to the fact they still need to be met. If it needs individualising, you can start this off anonymously - I particularly liked the formulation, ‘Still waiting for 3 people...1 person...and we’re ready to go’ as a way to make individuals accountable without drawing negative attention to them.
