While tones played on instruments consist of a fundamental pitch and a series of softer partials, the Shepard Tone essentially has no single fundamental, and any partials are equal in volume. Upload images to make storyboards and slideshows. Risset has also created a similar effect with rhythm in which tempo seems to increase or decrease endlessly. This gave me a fever! It really is a simple technique to achieve. Shepard Tones, by including every octave of a pitch class within the audible range, essentially flatten the full breadth of the audible range into a single cycle of pitch classes. These tones consist of several sinusoidal components spaced by octave intervals.
