Another Nolan film, and another Nolan film scored by Hans Zimmer. When done correctly, the tone appears to rise (or descend) continuously in pitch, yet return to its starting note.

According to Shepard, "almost any smooth distribution that tapers off to subthreshold levels at low and high frequencies would have done as well as the cosine curve actually employed. Is there any science behind movie/commercial camera angle changes? a raised cosine function of its separation in semitones from a peak frequency, which in the above example would be B4. half an octave: Shepard had predicted that the two tones would constitute a bistable figure, the auditory equivalent of the Necker cube, that could be heard ascending or descending, but never both at the same time.

How to draw a truncated hexagonal tiling? Deutsch found that one person might hear the pattern as ascending in pitch, whereas another person would hear the same pattern as descending.

Overlapping notes that play at the same time are exactly one octave apart, and each scale fades in and fades out so that hearing the beginning or end of any given scale is impossible. "[11]), The early experiments, in collaboration with Jacqueline Metzler, used perspective drawings of very abstract objects: "ten solid cubes attached face-to-face to form a rigid armlike structure with exactly three right-angled 'elbows,'" to quote their 1971 paper, the first report of this research. Jean-Claude Risset subsequently created a version of the scale where the steps between each tone are continuous, and it is appropriately called the continuous Risset scale or ShepardRisset glissando.
