The theme first appeared in Dr. No in 1962, the opening film in the long-running James Bond series based on Ian Fleming's novels. Composed by Monty Norman and arranged by John Barry, its distinctive guitar riff and brass arrangement became the musical signature of the franchise, returning in some form across decades of films. Because the melody is recognised worldwide even by people who have never seen a Bond film, it has travelled far beyond cinema into television, advertising, parodies and online videos, where a few seconds instantly signal espionage, confidence and high-stakes style.
