Whale song has long been used online as a ready-made piece of ocean ambience, rather than coming from a single film, show or viral clip. Because the calls are instantly recognisable and carry no spoken words, editors can drop them into nature documentaries, meditation videos, sleep sounds and underwater footage without distracting from the visuals. The sound also works as a shorthand for vastness and calm, which is why it keeps appearing in relaxation playlists, travel edits and classroom clips about marine life.
