The melody is adapted from Gran Vals, a solo guitar piece written in 1902 by Spanish composer Francisco Tárrega. Nokia selected a short phrase from it in the 1990s and turned it into the default ringtone for its mobile phones, including models that sold worldwide during the early 2000s. Because so many people heard it daily, the tune became linked to mobile calls in general, not just one brand. It later spread online as a nostalgic sound for memes, parodies and videos recreating the era of physical keypads and limited ringtones.
