dun dun dun

An onomatopoeic representation of a three-note dramatic sting (“short musical phrase”), probably the seventh to ninth notes (E♭-C-F♯) from the start of the theme music of the American police procedural television series Dragnet (first broadcast 1967–1970), which was used for dramatic effect during various episodes. The tune, originally simply called “Main Title” and later “Danger Ahead”, was composed by the American composer Walter Schumann (1913–1958), based on the beginning of the theme music of the film The Killers (1946) by the Hungarian-American composer Miklós Rózsa (1907–1995).
