This World News Tonight theme is a composition by major Hollywood composer Hans Zimmer and his co-composer at Remote Control Productions Steve Mazzaro. They had previously worked together on the score for the Batman film “The Dark Knight Rises”. This theme is a total departure from the theme that ABC’s evening newscast had been using in some form or another since the late seventies. Although Zimmer has adapted his style for news music, the World News Tonight theme still sounds like a classic Hans Zimmer theme. He relies heavily on thumping, pulsating strings that evoke a sense of urgency, energy and determination. In musical terms it is called ostinato and in film scores it is often used to propel a scene forward which lacks dynamic visual action.
The result is a theme that sounds decidedly cinematic. It continues a trend of movie composers doing news themes that was started by NBC which commissioned John Williams in 1985 to compose The Mission. On Primetime Live movie composer Bill Conti composed the theme music. The theme debuted along with new graphics and a slightly refreshed set. ABC kept the theme when David Muir became anchor of the broadcast, though the open has been shortened.
