The melody comes from John Williams's score for Star Wars, first heard in the 1977 film and now one of the most recognisable themes in cinema. Fairground and organ-style versions have long been used to make the tune feel nostalgic and comic, stripping away its orchestral grandeur while keeping the notes instantly identifiable. Online, that playful reworking fits short videos, memes and parodies, where a few seconds of the theme can signal an epic moment without taking it seriously.
