The melody comes from Gran Vals, a guitar piece by Spanish composer Francisco Tárrega, and became globally known when Nokia adopted a short excerpt as its signature ringtone in the 1990s. Because so many phones used it for years, the tune spread far beyond advertising and became part of everyday life. Online, creators still use it as a shorthand for mobile nostalgia, ringtone humor and references to older devices, especially when a video needs an instantly recognizable phone sound with a melodic twist.
