The Nokia ringtone is adapted from Gran Vals, a 1902 guitar piece by Francisco Tarrega, and became the default sound on Nokia handsets in the 1990s. Models like the 3310 turned that melody into a global cue for a ringing mobile, especially in Brazil where the heavy, durable phones earned the tijolao nickname. Clips of the ring later spread through YouTube and meme edits, where it now marks retro technology, missed calls and phones that survive any drop.
