Toccata and Fugue in D minor, BWV 565, is a pipe organ work attributed to Johann Sebastian Bach and composed in the early 1700s. Its opening became widely known beyond classical music through films, cartoons and horror parodies, especially its long association with Dracula, haunted mansions and mad scientists. Television, Halloween playlists and internet memes kept the motif alive as shorthand for old fashioned spookiness. Today creators reuse the short opening more than the full piece, because a few seconds instantly set a gothic scene without any explanation needed.
