THE APPARITIONS IN THE OPERA OF “FREISCHÜTZ.”
The army of demons and ghosts which pass over the stage in the “Freischütz” manage in various ways; in some cases a movable scene is used, and in others the uncanny creatures are painted upon a canvas roll and are projected, by means of a powerful light, upon a scene representing clouds. Hissing, snapping, screeching, and other hideous noises are produced by means of whips, clappers, whistles, rattles, and other like devices behind the scenes.
