This is a modern version of the deep gong tied to The Undertaker, a single heavy resonant chime with a long dark ring lasting about four seconds. It feels theatrical, serious and slightly eerie, turning a quiet moment tense and ominous. It comes from the WWE entrance audio for The Undertaker, one of wrestling's most recognisable characters.
