Known as the Nokia Tune, this melody is based on a phrase from Gran Vals by Spanish classical guitarist Francisco Tárrega. Nokia introduced it as a mobile phone ringtone in 1994, and its repeated presence on widely used handsets made it one of the world’s most familiar electronic melodies. It later spread through remixes, parody calls, retro technology videos, and internet memes. Like the Windows XP shutdown sound, it remains popular because a few notes can immediately evoke an earlier era of consumer technology.
