Telegram is a popular messaging app, and its default notification chime has become familiar to millions of users who hear it many times a day. As the app grew into a major platform for group chats, channels, and private messages, the sound moved beyond phones and into short-form videos, where editors use it as shorthand for a message arriving. It remains popular because it is instantly recognisable, even without any on-screen text, and it immediately sets up an expectation that something new has just been said.
