The melody is the famous Marche funèbre from Frédéric Chopin’s Piano Sonata No. 2 in B-flat minor, composed in 1837 and long associated with funerals and state ceremonies. Its slow, solemn character made it a shorthand for death and mourning in film, television and cartoons for more than a century. Online, creators adopted the same tune for ironic RIP edits, pairing its grave tone with everyday fails, game overs and embarrassing moments. That contrast keeps it instantly recognisable, and the Spanish title Marcha Fúnebre is how many Spanish-speaking creators search for and share it.
