Sound design is also a major component of some shows.
This can range from music to sound effects such as thunderstorms or howling dogs. Think about what sounds you could actually hear at different points in history. Interestingly, Inverness, Scotland, where the castle for Macbeth stands, is on the banks of Loch Ness. Many theatre people have a superstition about saying the word Macbeth inside a theatre. They believe that the play is cursed and bad luck befalls anyone who mentions the murderers name.
