In this video I show you a sound that seems to continually rise in pitch but never actually does. "[3], According to the American Psychological Association, "nonmetric multidimensional scaling .. has provided the social sciences with a tool of enormous power for uncovering metric structures from ordinal data on similarities. You start with a Sine wave say on note A4 which sits at 440 Hz and you have it glissando down to A3 at 220 Hz over a period of time. 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. Hit "Start" again to stop the tone. This audio illusion is more than just a novelty, however, and filmmakers like Christopher Nolan have embraced it in their work. A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves.When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale.This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.

Complex Tones: multiple pure tone components Fundamental Frequency: Number of times a sound repeats per second First Harmonic . Creepy! Understanding Scale Degree Names (A Quick Crash Course). The scale as described, with discrete steps between each tone, is known as the discrete Shepard scale. The sound design for the Batpod, a hyper-futuristic motorcycle, utilizes an ascending Shepard-Risset scale so as to portray a motor that accelerates smoothly with no shifting required. That also helps explain why we hear the melody in this illusion sliding up like a barber pole without noticing the incoming lower tone. phenomenon of resolution in music theory.
