The Phantom of the Opera premiered in London in 1986, composed by Andrew Lloyd Webber with lyrics by Charles Hart, based on Gaston Leroux's 1910 novel. Its title track features Christine and the Phantom, but the instrumental organ motif became the show's signature sound in trailers, performances and recordings. The musical became one of the longest running shows in Broadway history, so the riff moved far beyond theatre into films parodies and online edits, where it now instantly signals gothic romance and melodrama without any context needed.
