Even if you can’t dance to the beat, your eyes can: A new study finds that people unconsciously blink in rhythm with music.

“Everybody has rhythm. It’s impossible to exist without it,” once said legendary musician Victor Wooten. And he may be more right than we realized. A new study shows that the intrinsic human relationship with rhythm runs so deep that even nonmusicians blink in rhythm with music.
The hidden rhythm inside of us
A team of scientists from the Chinese Academy of Sciences has published a study revealing a new way our bodies respond to music. They asked over 100 nonmusicians to listen to Western classical music without any further instructions. Then, the scientists investigated a variety of neural responses and brain structures. They recorded brain waves with electroencephalography (EEG), tracked eye movement, and measured how intensely specific brain regions are connected using diffusion-weighted imaging.
The scientists uncovered a surprising new entry into the list of ways we synchronize with music. Beyond the familiar, mostly voluntary movements like foot-tapping and clapping, they revealed that our eyes blink automatically along with the beat.
The neural basis of synchronization
“We found that people’s spontaneous eye blinks fall in step with the musical beat—even without being told to move—revealing a hidden link between hearing music and the oculomotor system,” says Yi Du, a co-author of the study. This finding is especially intriguing because none of the participants had a professional musical background, suggesting that the brain can recognize and predict rhythmic patterns without prior training.
When the scientists analyzed the recorded brainwaves, they found that listening to music makes your brain’s rhythm prediction centers actively signal the muscles that control blinking, the oculomotor system. The strength of a person’s blink synchronization was linked to the white matter microstructure in a key sensorimotor pathway in the left hemisphere of the brain. Surprisingly, the imaging data showed that individuals whose neuronal fibers are less dense in these areas actually showed better synchronization between their blinks and the beats. The researchers propose that more efficient wiring rather than just more wiring may underlie this type of sensory communication.
Blinking falls out of rhythm when attention shifts
The researchers also showed that the spontaneous alignment of blinking with musical beats occurs only during active listening. Once the participants were asked to focus on a task, detecting a simple visual target, a red dot on the screen, their eyes did not align with the rhythm anymore. This indicates that although this is an involuntary response to music, it requires a certain level of concentration.

A window into brain connectivity and sensory communication
Studies like these can help us understand how pathways in the brain connect and how different senses communicate. “This project reminded us that small, overlooked behaviors can expose big principles of brain function,” says Yi Du. The research team hopes that this easy-to-measure eye movement may serve as a tool in future to diagnose neurological conditions like autism spectrum or developmental language disorders that often involve rhythm and timing deficits.
This study was published in the peer-reviewed journal PLOS Biology.
