Gongs have been used for centuries in ceremonies, temples and traditional theatre across East and Southeast Asia, where a single strike could signal an announcement, mark a ritual moment or command attention. That ceremonial association carried into film, television and stage sound design, where the instrument became shorthand for grandeur, suspense and finality. As short-form video and livestreaming grew, creators adopted the clean, isolated gong strike as a ready-made punctuation sound, using it to underline reveals, jokes and transitions without needing dialogue or music.
