Listen to Chimps Drum—Researchers Say They May Have Musical Rhythm
Deep in the African rainforests, a male chimpanzee approaches a towering tree with wide buttress roots, grips its crest, and pounds with his hands and feet, producing a resonant, low-frequency boom that echoes for over a kilometre. This behaviour, known as buttress drumming, is a hallmark of chimpanzee communication, blending physical prowess with acoustic signalling.
Recent research, including a groundbreaking 2025 study in Current Biology, reveals that chimpanzees drum with distinct, non-random rhythms, suggesting a profound evolutionary link to human musicality. Western chimpanzees (Pan troglodytes verus) produce evenly spaced, metronome-like beats, while eastern chimpanzees (Pan troglodytes schweinfurthii) alternate short and long intervals, creating a swing-like rhythm.

These findings, based on 371 drumming bouts across 11 communities, challenge the notion that rhythmic abilities are uniquely human, indicating that the roots of musicality predate human evolution by millions of years. Drumming serves as a long-distance communication tool, encoding individual signatures and social cues, and varies by context, from travel to dominance displays.
This introduction explores the rhythmic complexity of chimpanzee drumming, its social and cultural significance, and its implications for understanding the origins of rhythm in humans. By examining this behavior, we uncover how our closest relatives use sound to navigate their world, offering a window into the shared evolutionary heritage that connects us across the forest canopy.

The Biology of Chimpanzee Drumming
Chimpanzees (Pan troglodytes) are our closest living relatives, sharing a common ancestor with humans roughly six million years ago. Their drumming behaviour involves striking the buttress roots of hardwood trees, which act as natural amplifiers, producing sounds that travel through dense forests.
A 2025 Current Biology study by Vesta Eleuteri and colleaguesanalysedd 371 drumming bouts across 11 communities of eastern (Pan troglodytes schweinfurthii) and western (Pan troglodytes verus) chimpanzees, revealing that their drumming is not random but follows structured rhythmic patterns.

Western chimpanzees drum with isochronous beats—evenly spaced like a metronome—while eastern chimpanzees use alternating intervals, creating a swing-like rhythm. This distinction suggests that rhythm is not only present but also varies culturally or socially, a trait once thought unique to humans. The physical act of drumming, often combined with pant-hoot vocalisations, requires coordination and strength, highlighting chimpanzees’ cognitive and motor capabilities.
The Mechanics of Buttress Drumming
Buttress drumming is a deliberate act, typically performed by male chimpanzees during travel, resting, or displays of dominance. The process involves selecting specific trees, often hardwoods like mahogany, whose buttress roots resonate effectively. A 2022 Animal Behaviour study notes that chimpanzees are selective, choosing roots that produce louder, lower-frequency sounds that carry further than their vocalisations alone.

The drumming itself is rapid, with some western chimpanzees producing beats so fast they blur, as described by primatologist Catherine Hobaiter in a 2025 National Geographic article. Chimpanzees grip the tree with their hands and strike with their feet, sometimes leaping between buttresses in a dance-like motion. This physicality, combined with the integration of drumming into pant-hoots—loud, long-distance calls—suggests a complex communication system that conveys identity, location, and social status.
Rhythmic Patterns and Subspecies Variation
The 2025 Current Biology study provides the most extensive dataset on chimpanzee drumming to date, spanning nearly 25 years of recordings from six populations in Côte d’Ivoire, Guinea, Senegal, Uganda, and Tanzania. Researchers found that western chimpanzees drum with a consistent tempo, producing more hits per bout and integrating drumming earlier in their pant-hoot sequences, typically during the build-up phase.
Via SciTechDaily
Eastern chimpanzees, in contrast, delay drumming until the climactic scream and use alternating short and long intervals, creating a more variable rhythm. These differences are not tied to ecological factors like tree type, as both subspecies drum similarly within their regions regardless of forest density, according to the study.
Instead, social dynamics may drive these variations, with eastern locura eastern chimpanzees living in larger, more aggressive groups compared to the smaller, more egalitarian western groups, as noted by Hobaiter in The Guardian (2025).

The Evolutionary Significance of Rhythm
The discovery of rhythmic drumming in chimpanzees has profound implications for understanding the origins of human musicality. Rhythmic percussion is considered one of the earliest forms of human musical expression, characterised by non-random timing and isochrony. The Current Biology study suggests that these “building blocks of musicality” were present in our shared ancestor with chimpanzees, predating human evolution by millions of years.
As Hobaiter explains, “Our ability to produce rhythm seems to predate humans being human” (ScienceDaily, 2025). This challenges earlier assumptions that rhythm perception is uniquely human, as older studies suggested primates struggled with beat synchronisation.
Via National Geographic
A 2015 Scientific Reports study on a captive chimpanzee named Barney provided early evidence of rhythmic drumming, but the 2025 research confirms this in wild populations, showing that chimpanzees not only drum rhythmically but also exhibit regional variation, akin to human musical traditions.
Comparison to Human Musicality
While chimpanzee drumming shares structural similarities with human music, it is not music in the human sense. Humans use rhythm to create art, coordinate group activities, and express emotions, whereas chimpanzees drum primarily for communication. However, the presence of non-random timing and subspecies-specific patterns suggests a shared evolutionary foundation.
Via NBC News
A 2025 New Scientist article notes that chimpanzees’ rhythmic abilities align with human musical features like isochrony, seen in evenly spaced beats across cultures. Unlike humans, chimpanzees do not synchronise their drumming with others or dance to it, though they exhibit dance-like “rain dances” in response to natural rhythms like thunderstorms (Discover Wildlife, 2025). These behaviours hint at a proto-musical capacity that may have evolved into human music through social and cognitive advancements.
Challenges in Studying Chimpanzee Drumming
Collecting data on chimpanzee drumming is a monumental task due to the dense, cacophonous nature of rainforests. The Current Biology study required over a century’s worth of cumulative fieldwork, involving researchers from multiple institutions across Africa. Recording clear audio in the wild is challenging, as background noise often obscures drumming sounds.
Via BBC
Researchers like Eleuteri relied on long-term observation and advanced acoustic analysis to isolate and measure inter-hit intervals, confirming their rhythmic nature. The study’s success highlights the importance of collaborative, long-term research, but ongoing habitat destruction and population declines threaten future studies. A 2025 NPR article notes that hunting, the pet trade, and deforestation are depleting wild chimpanzee populations, making such research increasingly urgent.
Conservation Implications
The discovery of rhythmic drumming underscores the need to protect chimpanzee populations and their habitats. Each community’s unique drumming style represents a form of cultural heritage, as emphasised by Hobaiter (BBC Science Focus, 2025). Losing a population could mean losing irreplaceable behavioural diversity.

Deforestation in West and East Africa, driven by logging and agriculture, is shrinking the rainforests that support drumming trees. Conservation efforts, such as those led by the Jane Goodall Institute, focus on protecting habitats and reducing human–chimpanzee conflict. Community-based initiatives, like ecotourism, provide economic incentives for locals to preserve forests, ensuring chimpanzees have the space and resources to continue drumming.
Broader Implications for Animal Rhythmicity
Chimpanzee drumming adds to a growing body of evidence that rhythmic behaviours are not exclusive to humans. A 2020 Proceedings of the National Academy of Sciences study found that chimpanzees can sway rhythmically to music, while sea lions and parrots have been trained to bob or tap to beats (Scientific Reports, 2015). However, chimpanzees are unique in exhibiting spontaneous, culturally variable rhythms in the wild, without human training.
Via the University of York
A 2025 Science Advances study on chimpanzee vocalisations suggests that their ability to combine calls with drumming may represent a stepping stone toward human language, which relies heavily on rhythmic timing. These findings challenge the notion that rhythm perception is a human-specific trait, opening new avenues for comparative research.
Future Research Directions
The Current Biology study paves the way for further exploration of chimpanzee drumming. Researchers aim to investigate how chimpanzees coordinate their hands and feet, how rhythms influence social interactions, and whether tree selection affects sound quality. Hobaiter is particularly interested in whether chimpanzees have an aesthetic appreciation for their drumming, noting their preference for resonant hardwoods (Discover Wildlife, 2025).

Future studies could use machine learning to analyze larger datasets, mapping rhythm variations across more communities. There is also interest in studying juvenile chimpanzees to understand how drumming styles are learned, potentially confirming cultural transmission. Such research could further illuminate the evolutionary roots of rhythm and its role in social cohesion.
Ethical and Philosophical Considerations
The rhythmic abilities of chimpanzees raise ethical questions about their conservation and treatment. If their drumming represents a form of proto-musicality, it underscores their cognitive complexity, strengthening arguments against their use in invasive research or captivity.
Via IFLScience
Philosophically, their rhythmic behaviors challenge human exceptionalism, suggesting that cultural and communicative traits once thought unique to humans have deeper evolutionary origins. Protecting chimpanzees means preserving not just a species but a living link to our shared past, offering insights into the origins of music, language, and social behavior.
Do Chimps Have Rhythm? Stunning Audio Suggests They Might
Chimpanzee drumming, with its structured rhythms and subspecies variations, reveals a profound connection between humans and our closest relatives. The 2025 Current Biology study demonstrates that chimpanzees drum with purpose, using non-random, culturally distinct patterns to communicate across vast distances.
These findings suggest that the roots of human musicality stretch back to our shared ancestor, challenging assumptions about rhythm as a human-specific trait. As conservation threats mount, protecting chimpanzees and their habitats is crucial to preserving their unique drumming traditions. By listening to their beats, we gain a deeper understanding of our rhythmic heritage, reminding us that the pulse of life resonates across species, echoing through the forests of our evolutionary past.
