The Shepard Illusion or Shepard Tone is frequently compared to an “auditory barbershop pole” - a famous optical illusion that makes the brain think that the stripes are moving either up or down rather than around the pole. Based on the context of how we’re listening to these tones, our brain hears each repeated tone as being either higher or lower than the one before. Each octave being played is created with tones that can create ambiguity and confusion when listened to in succession. Roger Shepard published a paper on the topic in 1967 explaining how and why this happens. “What have you done to my brain?” a third commenter wrote. “Will it ever sound high enough to satisfy what my brain wants? I’ve watched it for too long,” one person commented on the TikTok. In reality, the tones are not getting higher, it’s the same sequence of notes, and the illusion can be applied to the tone decreasing in pitch too. When listening to the tones over and over, the TikTok does seem like it’s on a loop and that the tone just keeps getting higher and higher. “The sound isn’t actually getting higher, but your brain thinks it is, which is why you’re probably thinking…” and then the TikTok loops back to the opening statement, “There’s no way this is a loop.” “This is an auditory illusion,” McBride writes in the video. The video starts out with, “There’s no way this is a loop” and transitions to McBride listening to a series of tones.
