The tone is credited to Shoji Meguro, the longtime composer for Atlus and the Persona series of Japanese role-playing games known for their stylish menus, phone messages and jazz-influenced soundtracks. Clips in this style circulated among fans who extracted in-game alerts to use as real phone ringtones and text tones. From there it spread to soundboards and short-form video edits, where the short chime signals a message arriving. It remains popular because it is instantly readable, very short, and carries the distinctive polished sound design Persona is known for.
