The technique of
interruption pervades all levels of the stage work of the
German modernist theatre practitioner Bertolt Brecht—the
dramatic,
theatrical and
performative. At its most elemental, it is a formal treatment of material that imposes a "freeze", a "framing", or a change of direction of some kind; something that is in progress (an action, a gesture, a song, a tone) is halted in some way.
