Instagram's notification chime comes from the app itself, where it alerts users to likes, comments, follows and direct messages. As short-form video editing grew, creators began lifting the one-second sound out of the app and dropping it into memes, skits and reaction videos to instantly signal that a phone had just buzzed. It works because almost everyone recognises it without context, much like the Discord notification for other platforms. Its brevity and familiarity keep it popular for comedy, commentary and social media parodies, where a single ding can set up a joke about attention, validation or constant phone checking.
