Wow! A great example of what happened to my brain at a Who concert in 1968.

Amazing! It almost looked like a liquid the way they adjusted at the same time.

Can anyone offer a scientific explanation for this?

The thought occurred to me that maybe our ears recognize pitch in ways similar to the way our eyes recognize shape. That is, pitch forms a pattern in the ear, by exciting nerves in a geometric shape of nerve endings that the brain has learned to recognize as pitch. Just as the rods and cones in the eye transmit data about geometric shapes to the brain, which has learned to perceive them as physical shapes in the universe that is reflecting the light.

The shapes probably have more to do with the speaker generating the sound than the sound being generated. A sound is just a wave - the shorter the wavelength, the higher the pitch.

I could see that being one type of a quality control test for a speaker manufacturer - check for symmetry, expected patterns, etc.
