Mehter music comes from the Ottoman military bands that accompanied armies and ceremonies with drums, zurna and cymbals, a tradition that has become shorthand for grandeur and authority in Turkish popular culture.

Diamond Mehter fits that pattern: a five-second burst that needs no context to signal that something important, or absurdly self-important, is arriving, which is why editors keep reaching for it for entrances and reveals.
