Infants begin to shape their movements in response to music within their first year of life, though the ability to coordinate these actions with a rhythmic beat develops later, according to research published in the journal eLife. A study led by Trinh Nguyen of the Istituto Italiano di Tecnologia (IIT) and the University of Vienna tracked 79 infants aged three, six, and 12 months to determine how the brain transforms auditory perception into motor activity.
How does music influence infant movement?
Researchers discovered that while infants process music early in development, spontaneous movement patterns change significantly as they reach their first birthday. By using EEG recordings and automated video-based motion-tracking—specifically DeepLabCut software—the team found that 12-month-olds moved more frequently when listening to music compared to “shuffled” or disorganized versions of the same songs. According to the study, this increased activity was primarily observed in the upper body and limbs, including motions like rocking, swaying, and arm-pedalling.
Infants under 12 months old do not show a significant difference in movement quantity when listening to structured music versus shuffled versions, suggesting that the brain’s ability to “dance” is a developmental milestone that matures over time.
Why does the brain respond to music before movement?
The study suggests that music processing begins well before a child can coordinate complex motor responses. When the research team analyzed event-related potentials (ERPs) from the infants’ EEG data, they found that all age groups—including those as young as three months—exhibited an enhanced auditory response to music. Trinh Nguyen notes that this increasing complexity is likely linked to the maturation of the dorsal auditory stream, a brain pathway essential for rhythmic entrainment.
While the brain recognizes musical structure early on, the motor system takes longer to catch up. The researchers observed no evidence that infants of any age could coordinate their movements precisely in time with the beat. This indicates a two-stage developmental process: first, the brain learns to encode musical information, and later, it gains the motor control necessary to translate that information into synchronized movement.
What are the future implications for developmental research?
Future studies will likely focus on what happens after the first year of life as children begin to develop more intentional, dance-like behaviors. Senior author Giacomo Novembre, a Principal Investigator at IIT, suggests that these early motor responses may represent a biological predisposition for musical engagement. As researchers continue to explore these patterns, they hope to uncover the functional significance of why humans are naturally drawn to move to music.
When observing infant development, focus on the distinction between “spontaneous movement” and “rhythmic coordination.” The former is an early biological response, while the latter is a skill that emerges as motor control refines.
Frequently Asked Questions
Do infants prefer specific types of music?
The study found that infants responded to the structure of music rather than specific pitches. Regardless of whether the music was high or low-pitched, 12-month-olds consistently showed higher movement levels for organized songs compared to shuffled versions.
At what age do babies start dancing to the beat?
The research indicates that even by 12 months of age, infants do not yet coordinate their movements in time with the music. While they move more in response to music at this age, the ability to “keep a beat” develops later in childhood.
Why is this research important for brain science?
Understanding how the brain transforms perception into action provides insight into the fundamentals of human musicality. It helps neuroscientists map how the dorsal auditory stream matures during the first year of life.
