In 403 BCE, Athens was tearing itself apart. After a bloody civil war between democrats and oligarchs, with bodies piling up in the streets, a democratic herald named Cleocritus called out desperately across enemy lines: “Fellow citizens, why do you drive us out of the city? Why do you wish to kill us?… We have been companions in the chorus, schoolmates and brothers in arms.”Footnote 1
Remarkably, his words worked. The opposition soldiers laid down their weapons. Of all the shared experiences Cleocritus could have invoked—military service, education, citizenship—he led with their memories of dancing and singing together in choruses. For the ancient Greeks, this was not just nostalgia. It was a visceral reminder of what historian William McNeill calls “muscular bonding”—the profound psychological and social transformation that occurs when groups move together in synchronized rhythm.Footnote 2
This ancient insight has never been more relevant. As democratic institutions face unprecedented challenges and communities fracture along political lines, I’ve been exploring how the Greek practice of choreia—collective singing and dancing—might offer unexpected paths toward civic healing. Working with Australian and American military veterans, secondary school and university students, working professionals, and interdisciplinary teams of cognitive scientists, performance scholars, and theatre practitioners, we are discovering that these ancient practices generate measurable improvements in empathy, social cohesion, and collective decision-making.
1. The body remembers what the mind forgets
Most people know Greek tragedies for their famous protagonists—Oedipus discovering his terrible fate and Antigone defying tyranny. But for ancient audiences, the heart of these performances wasn’t the individual heroes but the chorus: groups of citizen-amateurs who trained for months to perform intricate combinations of synchronized dance, music, and song. In democratic Athens, nearly every citizen participated in choruses at some point and created a shared vocabulary of movement and rhythm that transcended social divisions.
Unlike modern assumptions about virtue being a matter of rational choice or moral reasoning, the Greeks understood that ethical behavior could be quite literally danced into being. Young Athenians did not just learn about reverence, justice, or courage through philosophical discussion—they embodied these virtues through coordinated movement in sacred spaces, feeling their proper place in relation to others through the positioning of their bodies, the matching of their breath, and the harmony of their voices.Footnote 3
This is where contemporary research begins. Neuroscientists are beginning to understand what happens when people engage in synchronized group performance. The results are striking: participants show increased activation in brain regions and the release of neurochemicals associated with empathy and social bonding, improved capacity for perspective-taking, and enhanced feelings of belonging that persist long after the performance ends.Footnote 4
After nearly a year of a reign of terror and the abolition of democracy, Cleocritus managed to remind the supporters of the oligarchs of these special experiences that once bound them in profound ways to their exiled opponents. He was activating embodied memories. Even Plato noted that the effects of musical discipline eventually wear off. This is why the gods provided us with regular religious festivals full of choral movement, rhythm, and harmony to discipline ourselves once more and to reactivate the effects of choral training in performers and spectators for the health of the community.Footnote 5
My own research with my colleague at the University of Sydney, Professor Peter Wilson, Paul O’Mahony of Out of Chaos Theatre, and with colleagues Professor Kate Stevens and Dr. Jose Hanham at the MARCS Institute for Brain, Behaviour and Development at Western Sydney University uses state-of-the-art audiovisual and motion capture technology and psychological assessments to investigate the sustainability and reactivation of these synchronicity effects in participants who find themselves at odds with one another.
2. Warriors and students: Testing ancient medicine
We have watched as veterans discover new languages for experiences that often resist conventional expression. One Marine veteran in a pilot program explained, “What we’re writing and what we all are choosing to do is unadulterated. It’s coming straight from us. It’s based on the ancient material, and it’s just a clear, clean voice from real veterans… people that have paid a big price.” While seated in the audience, the spouse of another combat veteran said she was hearing details for the first time of what he endured decades before.
The key is not just performing these ancient texts; it is the months of collective training, the gradual synchronization of movement and voice, and the negotiation of shared space and rhythm. Veterans who struggle with reintegration find themselves naturally falling into step with others, their bodies remembering how to be part of something larger than themselves. The “fog of war” that obscures moral decision-making in combat finds its counterpart in the clarity that emerges from moving together toward a common artistic goal.
Similarly, with secondary school students on the cusp of civic adulthood, we are seeing how choral training creates unique spaces for exploring ethical complexity. Rather than debating abstract principles, students embody different perspectives through their bodies, literally stepping into various viewpoints as they move through the performance space.Footnote 6 They learn that wisdom is not just knowing the right answer but understanding how to move with others when certainty is impossible.
Our work builds on pioneering projects by Jonathan Shay, Bryan Doerries, and Peter Meineck, who have demonstrated the therapeutic power of ancient drama for military veterans.Footnote 7 But we are taking this further, not just observing that these interventions work, but investigating how and why they work at neurological, psychological, and social levels.
3. The science of synchrony
What exactly happens when people sing and dance together? Research in this area reveals multiple interconnected mechanisms. Synchronous movement creates a neurological experience of shared action even among observers. Coordinated breathing and vocalization trigger the release of endorphins and oxytocin—the same neurochemicals involved in social bonding and trust. The cognitive challenge of maintaining complex choreography while singing creates what psychologists call “cognitive load,” which can actually reduce self-focused attention and increase group identification.
Studies comparing synchronized versus non-synchronized group activities show that synchrony specifically—not just group activity—drives these effects. Participants randomly assigned to synchronized movement conditions show significantly greater increases in cooperation, trust, and willingness to help others compared to those performing the same activities without coordination.Footnote 8
But perhaps most importantly, choral performance creates what we might call “embodied democracy.” Unlike modern democratic participation, which often feels abstract and individualistic (e.g., casting a ballot or signing a petition), ancient choruses required citizens literally to move together, to negotiate space, timing, and expression in real-time. This was not metaphorical; it was democracy as physical practice, repeated until it became muscle memory.
4. The democracy of difference: Creating unity from diversity
What our research reveals—and what the Greeks understood intuitively—is that choral synchrony is never actually perfect unison. Instead, it is the “impression of uniform, unison movement”: the carefully negotiated appearance of unity that emerges from sometimes radical diversity.Footnote 9 No two bodies move identically. Yet to observers, they appear as one.
This is where choreia becomes more than a metaphor for democracy—it becomes its training ground. In ancient Athens, choruses drew members from different tribes, mixing citizens of varying social backgrounds and physical capabilities.Footnote 10 A wealthy aristocrat with formal dance training might stand next to a potter’s son who’d never performed. One man might have a dancer’s flexibility; another, a smith’s strength but stiff joints. Different heights meant different stride lengths. Different lung capacities meant different abilities to sustain long phrases.
The months of training were not about erasing these differences but about mapping them, understanding them, and creating collective strategies that worked within everyone’s limits. The tall chorister learned to shorten his stride; the short one to stretch. The flexible performer might take his place in the front row while the less agile one moved less conspicuously behind. They had to watch each other constantly, adjusting in real time, reading bodies like democrats must read the room.
This is precisely what we observe in our contemporary workshops. Veterans with combat injuries modify movements, and the group adjusts around them without breaking formation. Students with dance backgrounds learn to dial back their technique to match those encountering movement for the first time. As one participant noted, “It’s not about being perfect together—it’s about being imperfect in the same way, at the same time.”
The chorodidaskalos (chorus trainer) could not impose uniformity from above but must have facilitated this collective negotiation. Through trial and error—what we might now recognize as an iterative democratic process of kinesthetic deliberation—the group discovered what worked. They found their collective center, not through eliminating outliers but by expanding the circle to include them. The strongest supported the weakest; the most skilled created space for beginners to succeed.
This process of mutual accommodation, of finding shared rhythm despite different capacities, transforms abstract democratic principles into embodied knowledge. When citizens learn to breathe together despite different lung capacities, to step together despite different stride lengths, and to sound together despite different vocal ranges, they are not just performing democracy—they are literally practicing it. Every rehearsal becomes a lesson in compromise, attention to others, and collective problem-solving.
Groups that acknowledge and work with these differences—rather than trying to eliminate them—develop stronger social bonds and greater empathy. The process of creating unison effects requires participants to know each other intimately: who tires first, who tends to rush, and who needs extra counts to turn. This deep knowledge of others’ capacities and limitations, gained through hours of physical negotiation, creates the kind of interpersonal understanding that democratic deliberation requires but rarely achieves through words alone.
5. From ancient Athens to contemporary crises
This research arrives at a crucial moment. Trust in democratic institutions sits at historic lows. Political polarization threatens social cohesion. Young people report unprecedented levels of isolation and anxiety about civic participation. The rational discourse that supposedly underlies democratic deliberation seems increasingly inadequate to bridge our divides.
The ancient Greek solution wasn’t to abandon reason but to recognize its limits. They understood that before citizens could deliberate together productively, they needed to feel themselves as part of a collective body. This is what choruses provided—not through ideology or argument, but through the simple, profound act of breathing, moving, and sounding together.
Our contemporary adaptations do not attempt to recreate ancient Athens. Instead, we are discovering how these fundamental human technologies of synchrony and collective performance can be translated into modern contexts. Whether it’s veterans processing trauma, students navigating ethical complexity, or communities seeking common ground, the ancient insight remains powerful: sometimes the body must lead where the mind cannot yet follow.
6. The dance of democracy
As our research continues across Australia, the UK, and the USA, we are building an evidence base that challenges conventional assumptions about civic education and community healing. The implications extend beyond classical studies or performance theory to fundamental questions about how democracies cultivate engaged citizens and heal social wounds.
The story of Cleocritus reminds us that even in the darkest moments of civic breakdown, the memory of moving together can call people back to their shared humanity. In our fractured present, as we struggle to find languages adequate to our divisions, perhaps it’s time to remember what many Greeks knew: sometimes the most profound civic education happens not through words but through the shared rhythm of bodies moving together in time.
This is not about nostalgia for an idealized past or naive hopes that dancing can solve complex political problems. It is about recognizing that human beings are embodied creatures and that our capacities for empathy, cooperation, and collective decision-making are rooted in our physical experiences of moving with others. The ancient Greeks built this insight into the very foundations of their democracy. The question now is whether we are ready to learn from their example.
As we continue documenting how synchronized performance generates lasting changes in social cognition and behavior, we are not just uncovering the mechanisms behind ancient practices. We are potentially discovering new pathways toward civic renewal. In a world where traditional forms of democratic participation feel increasingly inadequate, perhaps it is time to remember that democracy was once, quite literally, danced into being.
