The sound comes from Telegram's desktop application, where it serves as the standard alert for an incoming message on a computer. As Telegram grew into a widely used messaging app, its clean two-tone chime became familiar to millions of desktop users, even outside the app itself. Video creators began borrowing it to signal a message arriving in skits, tutorials and meme edits, in much the same way as a Discord notification, because viewers instantly understand it without explanation. Its short length and neutral tone keep it useful today, fitting everything from comedy edits to realistic chat scenes without overpowering dialogue.
