BRO HOLD THE NOTE MORE SO THE ILLUSION IS STRONGER disclaim: will make you dizzy i think "The Shepard Tone is an audio illusion formed by overlaying separate tones separated by octaves that each rise/fall (depending on the nature of the Shepard Tone in question) and repeat independently of one another. As a result, in this case the sound seems to continuously get higher but never really does." -yutubr
