This melody comes from Love Story, the 1970 romantic drama whose theme music was composed by Francis Lai. The piece became widely known beyond the film through radio play, cover versions and its association with classic screen heartbreak. Online, short clips of the theme are still used because the tune communicates sadness immediately, even to viewers who have never seen the movie. That mix of old Hollywood emotion and instant recognizability keeps it useful for both sincere and ironic edits.
