ABSTRACTBy viewing the museum experience as inextricably linked to an interactive nexus of bodies and objects arranged in the museum space, this paper foregrounds the significance of movement in the shaping of museum encounters. Informed by the fields of dance, symbolic interactionism and multimodal social semiotics, it introduces a conceptualisation of visitorsâ movement as choreography unfolding either in compliance with the museum âscriptâ (scripted choreographies), or in response to prompts from other visitors sharing the same space (improvised choreographies). Attending to visitorsâ positioning and alignment as key resources of movement, the analysis of video data from two London galleries illustrates how visitors oscillate between performing âscripted choreographiesâ and âimprovised choreographiesâ through shifts in positioning and alignment, while being spectators of other visitorsâ choreographies. Both kinds of choreographies are continuously shaped in interaction with the âscriptedâ museum stage and other visitorsâ âscriptedâ and âimprovised choreographiesâ.
