The gong is a tuned percussion instrument with roots in East and Southeast Asia dating back thousands of years, used in ceremonies, orchestras and theatre to mark time and important moments. Recordings of a single strike became a staple stock sound effect for film and television, then spread online as a meme punctuation for dramatic entrances and fake profound statements. Its long sustain sets it apart from a short ding sound effect or a Taco Bell bong, giving editors a slower, more ceremonial impact that still reads instantly.
