The melody comes from Gran Vals, a 1904 guitar piece by Spanish composer Francisco Tárrega, adapted by Nokia as a selectable ringtone for the 2110 released in 1994, where it was listed simply as Type 7. As Nokia phones spread worldwide in the late 1990s and early 2000s, that short phrase became the default sound of mobile calls for millions of people. It later turned into online shorthand for old technology, with creators reusing the original monophonic version specifically to distinguish the first era of ringtones from later polyphonic remakes.
