Shepard Tone: A Pitch That Seems to Rise Forever

Sign in to see author· 1h ago

Curated archive entry based on published research. Layered tones separated by octaves can create a sequence perceived as continuously rising or falling in pitch, with no clear endpoint. This describes a documented perceptual effect under the cited conditions, not an independent personal report or evidence that the underlying physical measurements changed.
