On the Knocking On the Gate in ‘Macbeth,’ De Quincey explained that the knocking on the door was striking because it brought people back to real life from a vast transition. When the audience sees Duncan’s murder, they are in a state of shock, a moment that makes them hold their breath or freeze. At times of significant change, people remain silent. A knock breaks the silence that ensues on the door, and the viewer is quickly brought back to reality. This method creates a sense of warping time.
If we want to go through the radio, maybe we can do some white space, and then we can use Floye to pull the audience back from the white space. Or we can only use some pictures to help make the audience feel more involved.
