The sound comes from the Coffin Dance meme, which grew out of videos of dancing pallbearers in Ghana carrying a coffin while moving in time to upbeat music. Those clips were edited into fail videos in early 2020 and spread rapidly on TikTok and YouTube, where the tune became shorthand for an impending disaster played for laughs. The track itself is Astronomia, a high-energy electronic dance song, and its instantly recognisable brass melody helped the format stay popular long after the first viral wave.
