Elevator arrival chimes have been a standard feature of lifts for decades, designed to alert waiting passengers that a car has arrived and which direction it is travelling. The simple two-tone pattern became instantly recognisable from hotels, offices and shopping centres, and later from film and television lobby scenes. Online, creators adopted the same sound as a ready-made cue for arrivals, entrances and scene changes, because it needs no explanation. Its continued popularity comes from that shared familiarity, making it useful for comedy, vlogs and short-form edits.
