The sound comes from the trailers and score for Christopher Nolan's 2010 film Inception, where Hans Zimmer's low brass motif became instantly recognisable as a signal for epic, mind-bending drama. Other film trailers copied the style so widely that the blast became shorthand for a huge reveal, and editors soon lifted it into YouTube videos, memes and TikTok edits. It endures because a single hit can make almost any moment feel monumental without a single word of dialogue.
