The guidance gives details of a five-stage roadmap to bring the performing arts back safely. These five stages of the phased return to performing arts are as follows:
Stage One - Rehearsal and training (no audiences)
Stage Two - Performances for broadcast and recording purposes
Stage Three - Performances outdoors with an audience and pilots for indoor performances with a limited socially-distanced audience
Stage Four - Performances allowed indoors and outdoors (but with a limited socially-distanced audience indoors)
Stage Five - Performances allowed indoors / outdoors (with a fuller audience indoors)
