Cognitive scientist Henkjan Honing has published a peer-reviewed essay in Current Biology that pulls together two decades of evidence from genetics, neuroscience, and infant research to argue that humans do not simply learn music from their culture, but are born with a biological basis for musicality. The essay reframes a long-running debate and may influence how scientists, educators, and parents think about musical development.
From Cultural Product to Biological Trait
For most of the twentieth century, researchers treated music as a cultural invention, something societies build and pass down rather than something rooted in biology. Honing’s essay, which synthesizes interdisciplinary advances across developmental psychology, comparative animal research, and neurogenetics, challenges that assumption head-on. He argues the field has undergone a fundamental shift: the focus now falls on “musicality,” defined as the set of perceptual and cognitive capacities that allow humans to process rhythm, pitch, and timing, rather than on “music” as a finished cultural product.
That distinction matters because it changes the research question. Instead of asking why different societies produce different styles of music, scientists can ask what shared biological machinery makes any music possible at all. Honing treats musicality as central to human life, arguing that it appears early and consistently enough across populations to be difficult to explain by learning alone. If musicality is part of our species-typical endowment, then music is not just an art form but an expression of a deeper biological design.
Newborns Already Track the Beat
Some of the strongest evidence for an inborn musical capacity comes from studies of infants only hours or days old. A foundational experiment published in the Proceedings of the National Academy of Sciences used electrophysiological measures on newborns and found that their brains could detect the beat in music. Because these participants had virtually no postnatal exposure to musical culture, the results point to a capacity that is present at or extremely near birth.
A separate experiment published in PLoS Biology in 2026 sharpened the picture. Researchers including Roberta Bianco and Giacomo Novembre showed that newborns form musical predictions based on rhythmic structure but not melodic structure. Infants could anticipate when a beat should land, yet they did not track pitch-based patterns in the same way. The authors suggested that melodic tracking may develop later, gaining weight through exposure to communicative signals such as speech. That split between rhythm and melody in the earliest days of life hints that the biological toolkit for music is not a single switch but a set of capacities that unfold on different timelines.
Earlier research from Cornell University adds historical depth to this finding. Studies published in Psychological Science and PNAS found that young infants could detect rhythmic patterns from unfamiliar musical traditions more easily than adults could. That cross-cultural sensitivity appears to narrow with age, suggesting that biology may open a wide perceptual window and cultural exposure can gradually tune it. Infants start out broadly tuned to many possible musical systems, then specialize in the patterns they hear most often.
Genes and Brain Wiring Before the First Lesson
If musicality has biological roots, those roots should show up in the genome and in brain structure, and recent work suggests they do. A large-scale genome-wide association study in Nature Human Behaviour identified common genetic variants associated with beat synchronization. The study demonstrated high polygenicity, meaning the ability to keep time with a beat is influenced by many genes rather than one or two. Validation work in the same project tied a self-report rhythm measure to actual performance, strengthening confidence that the genetic signal reflects real-world musical behavior rather than survey noise.
On the neuroimaging side, a longitudinal study in Cerebral Cortex tracked children from infancy to school age and found that white-matter measures taken in infancy predicted later music and rhythm aptitude. The finding provides concrete imaging markers for early neural predispositions toward musicality. Infants whose brain wiring showed particular patterns in auditory and motor pathways tended to perform better on later rhythm and melody tasks, even when controlling for some environmental factors.
That caveat is significant. Genetic associations and infant brain scans can show correlation, but they do not prove that biology acts alone. A Harvard Graduate School of Education analysis noted that much research has documented the positive effects of musical training, and that environmental factors such as family resources, access to instruments, and cultural value placed on music can shape a child’s musical aptitude. Biology may load the dice, but experience still determines much of the outcome.
Why the Rhythm-First Pattern Challenges Assumptions
One of the most striking threads running through this body of research is the consistent primacy of rhythm over melody in early life. Newborns predict beats but not pitch contours. Infants detect foreign rhythmic patterns that adults miss. Genetic studies link common variants specifically to beat synchronization rather than to tonal sensitivity. Even older work on pitch processing in adults, published in Cognition, found that encoding pitch in musical contexts appears to be a domain-specific ability that can be localized in the brain, but the developmental timeline for that specialization is longer than for basic beat perception.
This rhythm-first profile challenges common intuitions about music, which often emphasize melody as the heart of a song. Honing and colleagues suggest that rhythm may instead provide the foundational scaffold on which other musical skills are built. From an evolutionary perspective, shared timing could have supported coordinated movement, group rituals, or proto-language, with pitch-based systems layering on later. The infant data are consistent with that story: the brain seems to lock onto temporal regularities before it carves up the frequency space into stable scales.
Rethinking Nature, Nurture, and Musical Training
Recognizing musicality as a biological trait does not imply that everyone is destined to become a virtuoso. Rather, it reframes individual differences. Some children may be born with neural and genetic profiles that make rhythm or pitch processing come more easily, while others may need more exposure and practice to reach the same level. Tools such as the National Center for Biotechnology Information databases have helped researchers integrate genetic and neuroimaging findings, but the field is still far from predicting personal musical outcomes from DNA or early scans.
At the same time, the biology-first view strengthens the case for early, inclusive music education. If infants already possess a basic beat-tracking system, then musical activities in the first years of life are not simply enrichment; they are opportunities to exercise and refine an existing capacity. Programs that encourage caregivers to sing, clap, and move with their babies may tap into this predisposition at a moment when the brain is especially plastic.
Researchers are also beginning to use digital tools to manage the growing literature on musicality. Personalized accounts on platforms like My NCBI allow scientists to save searches on topics such as rhythm perception or auditory development and receive automatic updates when new studies appear. Curated bibliography collections can then be shared across labs, helping to coordinate efforts in what has become a highly interdisciplinary field.
A Biological Capacity, Culturally Realized
Honing’s essay does not deny the power of culture; it insists that culture works on a prepared mind. Musical systems differ dramatically around the world, from microtonal scales to complex polyrhythms, yet they all seem to fit within the boundaries of what the human brain can parse. Honing’s essay and the studies it discusses suggest that musicality may be an evolved capacity, while specific musical traditions are cultural solutions that explore and elaborate that capacity.
For scientists, this framing encourages new kinds of questions: Which aspects of musical structure are dictated by biology, and which are historical accidents? How do genetic and neural predispositions interact with particular learning environments? For educators and parents, it offers a practical takeaway: children arrive ready to engage with music, and early experiences can either cultivate or neglect that readiness. Far from being a luxury, music may be one of the most natural ways humans have found to express the rhythms and patterns already written into their brains.
