The Nokia Tune comes from a phrase in Gran Vals, a solo guitar composition by Spanish composer Francisco Tárrega. Nokia adopted the melody for its mobile phones in the 1990s, and it became one of the world’s most recognizable ringtones. Later handset versions changed its tone and arrangement while preserving the central melody. Online, creators use it alongside other nostalgic computer and device audio, including the Windows XP shutdown sound. It remains popular because listeners can identify both the tune and its mobile-phone association within seconds.
