Make use of science to make movies.
Director Christopher Nolan continues to take pictures of the finest SF entertainment that adults can enjoy, such as the movie "Dark Knight" series, "Inception", "Dunkirk". I think that various techniques are used for his work, but secrets are hidden not only in video but also in sound.
It is a magic of sound "infinite scale ~ Shepherd tone" derived from psychologist Roger Shepard. "It sounds like the scale is getting higher, but it's not actually really high," it's a mysterious sound loop.
For example, if you think that you arrived at the summit like Escher's "House of Stairs" and a signboard that the red and white on the barber turns round, it is an image as if you had returned to the departure point unintentionally.
Roughly, please try to grasp the atmosphere with Clorox Regular movie.
First see the video of Shepard Tone
How do you make use of this in Nolan work? Please check the videos of Vox. It matches the image much more natural than the above video, and may not notice it unless you concentrate in the play.
The tick-off sound of "Dunkirk" is a director's wristwatch.
Well, the mechanism of the infinite musical scale, while flowing the Doremifa Solasi, which is the fundamental tone, at a certain volume, the doctor above one octave from the volume large to the small, the one below the octave from the volume small to the large By repeatedly playing, the ear arises as if one 'octave is looping'. This technique seems to be helping that the ' brain is a misunderstanding ' as it goes up to Doshi and then continues to Doshi which is one octave higher.
Also according to Huff Post , even if one can hear the fundamental tone and the harmonic (the tone having the frequency twice than the fundamental tone equal the treble) at the same time, only one of them can be recognized , and only the musical scale close to the treble heard at the end can be heard It is one factor that creates this illusion.
The difficult thing is put on, the director seems that this technique is a favorite of the great, and infinite scales are adopted for almost all his works. In the movie "Prestige", repeated various researches on composer David Julian and various techniques on his technique, succeeded in putting emotional height and the like into music by a mathematical approach. This gives the viewer a feeling of continuous tension, and it creates an effect to unease anxiety.
Movie music is not only beautiful or matched to the picture, but also draws viewers based on these scientific grounds.
