Attach rehearsal material to the intended part and edition
Start with director-approved recordings, cues and part definitions. Decide how a member chooses the correct part and whether that choice applies to one session or a broader rehearsal plan. Keep the edition of the material explicit so later corrections do not silently change an unfinished attempt. If members change parts, agree whether they restart, continue at a shared step or choose a new session. The choir team owns the rehearsal content and its teaching decisions.
