Hans Zimmer (Dunkirk) Dunkirk
Hans Zimmer's score for Dunkirk uses an auditory illusion called a Shepard tone — layered frequencies that appear to rise endlessly in pitch without ever actually doing so — to create a sense of mounting tension that never resolves. The ticking of Christopher Nolan's own pocket watch is embedded in the opening cues, providing a metronomic pulse that runs beneath the entire film.
The score was designed to merge with the image, not accompany it
Zimmer's fifth collaboration with Nolan was the most closely supervised. Nolan was involved in every aspect of the scoring process — more than on any previous film — and the goal was to erase the line between score, sound design, and diegetic sound.
"I think on this one, we've come as close as anybody ever has" to completely fusing sound and image. — Hans Zimmer, Deadline (2018)
"This is the movie where Chris was the closest involved in every aspect of the score." — Hans Zimmer, Deadline (2018)
Nolan's pocket watch provided the score's rhythmic foundation
Before Zimmer wrote a note, Nolan recorded the ticking of his own watch and gave Zimmer the audio file. That ticking became the heartbeat of the score — a constant, metronomic reminder that time is running out.
"You hear the ticking of Chris' pocket watch and you know that this is what it's about." — Hans Zimmer, Deadline (2018)
Nolan had written the screenplay in a musical shape — the three timelines were conceived as rhythmic structures that would converge, and the script's formal ambition required a score that could sustain tension across the entire running time rather than providing traditional dramatic peaks and valleys.

The Shepard tone creates the illusion of endlessly rising tension
A Shepard tone is created by stacking sine waves an octave apart and sliding them upward simultaneously; as the highest frequency fades out, a new low frequency fades in, producing the perception of an infinite ascending scale. The effect has been shown to cause physical discomfort — headaches and nausea — in some listeners.
Zimmer has acknowledged that the Shepard tone is something he and Nolan had used before, but the Dunkirk score builds the entire musical architecture around it. The illusion mirrors the film's structure: three timelines at different temporal scales, intercut to create a sense of convergence that keeps escalating without arriving.
"There is a secret underlying this whole score that we're not going to give away." — Hans Zimmer, Deadline (2018)
The score avoids emotional cues by design
Zimmer and Nolan agreed that the score should not tell the audience what to feel. Instead, the combination of images and sound would create space for what Zimmer called "autonomous emotion" — the viewer's own response, unguided by conventional musical signaling.
"We didn't want to make it an emotional score. We thought it was the combination of the images and the sound that would let the audience come to their own autonomous emotion." — Hans Zimmer, Deadline (2018)
The instrumentation reflects this austerity: a string quartet, double bass, and fourteen cellos playing in unnaturally high register. Zimmer described the approach as reinventing the instruments — making them do things they had never been asked to do.
"It's basically a string quartet playing...making them do things that they have never done before." — Hans Zimmer, Deadline (2018)
Elgar's "Nimrod" anchors the homecoming
The score incorporates Edward Elgar's "Nimrod" from the Enigma Variations for the evacuation and homecoming sequences — slowed to six beats per minute and layered with added bass. The choice of "Nimrod" is loaded: the piece is one of the most recognizable musical expressions of British national feeling, played at Remembrance Day ceremonies and state funerals. Its appearance signals the shift from survival to collective meaning. (wikipedia)
The score was nominated for the Academy Award for Best Original Score at the 90th Academy Awards.
