The gong is a traditional Chinese percussion instrument long used in ceremonies, theatre, and temple rituals, where a single strike could signal an entrance, mark a moment, or command attention. On soundboards and in online video, that same dramatic ring has been repurposed as a versatile effect, from mock-serious reveals and game-show style moments to cinematic transitions. Its seventeen-second length gives creators room to let the sound breathe, and its familiar, resonant tone keeps it instantly recognisable even without any visual context.
