Macbeth opens with thunder and lightning as the three witches gather, and stage thunder has been part of the play ever since, signalling the supernatural and the disorder that follows. Modern productions and classroom performances still need a convincing storm sound that can be played on cue, which is why a dedicated thunderclap for Macbeth remains useful. Online, the same clip is reused by video editors for horror, Halloween and dramatic reveals, where a single realistic boom sets a dark mood faster than music or narration.
