The Mystery of the Shepard Tone Illusion Explained

The video explores the auditory illusion known as the Shepherd Tone, starting with basic ear tests using piano notes to understand pitch. It explains how the Shepherd Tone creates the illusion of an endlessly rising pitch by playing sets of notes separated by octaves. The video also introduces the tritone paradox, where notes seem to rise or fall in pitch depending on the listener's perception. The Shepherd Tone is named after Roger Sheppard, and the tritone paradox was first reported by Diana Deutsch.
