Christopher Nolan鈥檚 biopic on the theoretical scientist聽, who became known as the 鈥渇ather of the atomic bomb鈥, has an epic soundtrack.
We follow Oppenheimer鈥檚 early work in Europe, establishing the Los Alamos lab, the creation of the atomic bombs released on Hiroshima and Nagasaki, his later activism against nuclear development and its repercussions in his later life.
The music and sound design are integral to telling this dark story.
Ludwig G枚ransson鈥檚 score immerses the audience in the inner emotional dilemma of a man on the brink of unleashing the potential destruction of humanity, while the sound design illustrates flashbacks, physical phenomena and atoms clashing with each other.
Sound in Nolan鈥檚 films is characteristically loud and arresting, accompanied by epic music scores. Oppenheimer鈥檚 score moves from the gentle and personal to an imposing sound spectacle that heightens the intensity of the plot.
The violin forms the basis of the score. From the film鈥檚 opening track, the violin鈥檚 ability to shift from a hauntingly beautiful sound quality (or timbre) to a screeching descending melody to an intimate whispery tone draws us into Oppenheimer鈥檚 intense inner dilemma.
The violin is fitting to depict such a complex and intense character.
G枚ransson鈥檚 score draws on performance techniques with a rich cinematic and concert hall legacy.
滨苍听, the short, sharp screech of the violins played in repeated clusters punctuates the rising tension. This is echoed in Oppenheimer: to underscore the visuals of atoms spinning, G枚ransson layers string harmonics in an escalating crescendo of quivering energy.
In Mozart鈥檚 requiem (a mass of the dead)聽, the haunting simplicity of the opening melody played by the violins feels raw and immediately draws the listener in. Here, when the scientists learn of the bombing of Japan, the violin plays a two-note melody. This simple composition contains the enormity of the situation.
The violin is a fretless instrument, allowing traditional performance techniques including harmonics and vibrato.
Harmonics is an overtone you hear when you place your finger softly on the string and play with the violin bow. By not pushing the string down to the fingerboard, the string vibrates on both sides of your finger to create a whistling sound.
Vibrato is the tiny fluctuations in pitch caused by rocking the finger from the wrist or arm to create warmth and expressiveness in performance.
In this score, G枚ransson also employs non-traditional techniques such as tapping or hitting the body of the violin with the bow.
When these traditional and non-traditional performance techniques combine, the juxtaposition creates tension between the warm and more brittle sound qualities of the violin.
A scene in the classroom exemplifies the lyrical sound quality of violins that build in numbers. When Oppenheimer is alone one violin plays. As three people join him, three violins join in the composition. As the classroom fills 鈥 and as his excitement in talking about quantum physics grows 鈥 there is a build to the whole orchestra playing.
The violins shift to tension strings performing various rhythmic patterns and performance techniques. These combine with electronic instruments that musically fluctuate between hope, anxiety and despair.
As the scene progresses, the horns come thundering in as a warning of the destruction to come.
G枚ransson鈥檚 unrelenting score features in roughly 2.5 hours of the three-hour film. The orchestral blend of piano and harps runs alongside the sounds of Oppenheimer鈥檚 world. Feet stomping, synthesisers pulsing, clocks ticking and the electrical static of Geiger counters create a sound world of tension, dread and anticipation.
G枚ransson uses rhythmic techniques such as triplets 鈥 when three notes are played in the space of two 鈥 to build the intensity and to create escalating cross-rhythms during the聽.
The layers of strings playing harmonics and rhythmic patterns build in intensity to create an impression of momentum building. These techniques bring a sense of agitation, heightening the drama and building energy.
The music builds in intensity up to the moment of silence when the button is pushed: there is no turning back.
The score falling silent is as important as the music itself.

When Oppenheimer delivers his speech after the bomb was dropped on Nagasaki and Hiroshima, each jingoistic comment is followed by increasing applause and noise. When the sound suddenly drops out, we are left with his empty words.
When the film only includes the 鈥渘aked鈥 sound of the world on screen, we feel the gravity of the situation.
When we experience dynamic builds in anticipation in a music score, our dopamine levels聽. Sudden silence creates moments of intense focus. The contrast between the fullness of the orchestra and the silence immerses us in the world. We experience an emotional release.
The silence propels us into a feeling of suspended time: an almost deafening reminder of humanity through the use of close and intimate human sounds. It is one of the most potent features used throughout the three-hour film.
