Open an entrance scene with a door knock, then let it announce the visitor before the reveal lands. Follow it with a dramatic dun dun dun sting for a comic pause, or a bell ding when the joke is a friendly greeting instead of a scare.
About this sound
This short clip is a two-note door chime, the first tone low and hollow and the second a little higher and lighter, like a bell from a grand old mansion. It feels spooky without being frightening, playful and theatrical, turning an ordinary arrival into a knowing wink. It comes from The Addams Family, the long-running television and film franchise about a strange household.
