This article investigates a class room sequence with the methods of dance studies. Hence the teacher’s behaviour is seen as a stage performance. With a main method of dance theory, the Laban Movement Analysis (LMA) teacher’s handling of the classroom space, including body effort and shape, is analysed. Following Daniel Stern’s conceptualisation of forms of vitality I consider the teacher’s behaviour, focusing on the phenomenology and the temporal contour of feelings of anger. In terms of movement, this essay explores the dynamic experience of vitality affects.
