This meme sound is based on My Heart Will Go On, the theme song closely associated with the 1997 film Titanic and originally performed by Celine Dion. The recorder version spread online because the melody is instantly recognizable, while the shrill, amateur sound flips the song from heartfelt to hilariously awkward. It remains popular in short-form edits, reaction memes and parody videos whenever creators want a cheap-sounding emotional cue that viewers understand in seconds.
