This video-ethnographic study explores how professional actors and a director at the end of a theatrical rehearsal process coordinate transitions between rehearsed scenes. This is done through the development and use ofcues, that is, ‘signals for action’. The aim is to understand how cues are developed and how timing in transitions is achieved by using the designed cues. Work on three different scene transitions is analysed using multimodal Conversation Analysis. The results show that cueing is a central tool for developing (...) well-timed transitions, and how cues serve different purposes in the developing performance. There is no prior plan for how to achieve timely transitions. In all the analysed examples, it is an actor who must produce or act on the given cue who insists on its precise definition, followed by a negotiation on candidate cues, confirmation and specifying the cue. It is also actors who are primarily responsible for the timing of transitions, and the timing is solved through an interplay of clear-cut and embodied actions that allow for temporal variance. Cues are reflexively linked to actors’ observation and interpretation of other actors’ actions, which prevents a mechanical determination of timing in scene transition. (shrink)
