The Toreador March comes from Georges Bizet's opera Carmen, first performed in 1875, where its bold brass melody accompanies the bullfighter Escamillo. It later became widely known to a new generation through Five Nights at Freddy's, where a music-box version is linked to Freddy Fazbear and plays in the restaurant setting. Fans clipped that softer, eerier arrangement for memes, edits, and horror-themed videos, and it has stayed popular because the tune is instantly recognisable even in a fraction of a second.
