Ever notice how Christopher Nolans movies Interstellar, Inception, The Prestige feel like an anxiety attack Well, maybe thats overstating things a bit. But the director does have a knack for creating an unnerving degree of tension. Turns out hes using a little bit of musical magic to do it. The magic is actually a science based audio illusion called a Shepard tone. Named after psychologist Roger Shepard, a pioneer in our understanding of spatial relation, the effect sounds like an infinitely ascending or descending scale. The tones are constantly moving upwards or downwards, but they never seem to reach a pinnacle or nadir. This is accomplished by stacking scales on top of each othertypically one treble scale, one midrange, and one basswith an octave in between, then playing them in a continuous loop. A Shepard tone is sometimes referred to as the barber pole of sound. Next time you book a vacation for yourself, you should book one for your pooch as well.

Dont listen to this too long, or you might lose your mind Anyways, Christopher Nolan just loves this. With longtime collaborator Hans Zimmer, the acclaimed director has used a Shepard tone in almost every one of his films in the last decade. He even writes his scripts to match the effect. In a recent interview, Nolan explained how he used Shepard tones in his newest film, Dunkirk The screenplay had been written according to musical principals. Theres an audio illusion, if you will, in music called a Shepard tone and with my composer David Julyan on The Prestige we explored that and based a lot of the score around that. And its an illusion where theres a continuing ascension of tone. Its a corkscrew effect. Its always going up and up and up but it never goes outside of its range. And I wrote the script according to that principle. I interwove the three timelines in such a way that theres a continual feeling of intensity. Increasing intensity. So I wanted to build the music on similar mathematical principals. Knowing this, you gain a deeper understanding of films like Interstellar, Inception, and The Prestige. It also explains why these films seem somehow inconclusive. A Shepards tone creates a conflict that cant be resolved, just like Nolans plots. Digg, Business Insider.
