The melody most people recognise as the funeral march comes from Frédéric Chopin’s Piano Sonata No. 2, whose slow third movement, the Marche funèbre, was written in the late 1830s and later became closely associated with funerals and memorial services. Through films, cartoons and television it turned into a cultural shorthand for death and solemn endings, and online creators adopted the same association for comedy. Today it survives because a few sombre notes instantly tell an audience that something has ended, whether seriously or as a joke.
