4.4 million years ago, Ardi, one of the earliest Australopithecines, stood upright and took steps on two legs. While this moment marked the beginning of bipedalism, its effects stretched farther than we might imagine. These steps, both literal and metaphorical, forged a link between human motion and rhythm. And from that moment, the steady beat of walking left its imprint not just on human movement but also on music—a connection that shapes how our brains process sound and exertion today.

The Origin of Walking and Music
Ardi’s first steps created more than just a method of moving across the land. Walking became a way for early humans to experience rhythm—a steady, repetitive pattern that echoed through time. It wasn’t just about mobility; it was also about prediction. Recognizing footsteps helped create a sense of timing and anticipation. Each step built a sense of what was coming next, a rhythm inherent in walking that influenced how our ancestors moved, thought, and ultimately, made music.
Humans exist in a unique middleground—between the birds in the sky and the whales in the ocean. Birdsong reflects the erratic, quick movements of birds, while whale sounds flow as smoothly as their underwater glides. Human music, with its steady pace, mirrors the rhythm of walking. That’s why we often say music “moves.” Even though music doesn’t physically move from note to note, we perceive it as if it’s going somewhere—taking us on a journey. This fundamental connection to motion ties music back to the deep evolutionary roots of walking.
The Connection Between Human Motion and Music
Footsteps—the beat of our daily lives—are a core way humans experience rhythm. They compel us to track patterns, leading to our ability to anticipate and coordinate with external sounds. Songs, symphonies, and even simple tunes are structured to reflect these patterns, making walking a blueprint for much of human music.
If you compare this to animal sounds, the distinction deepens. Birdsong may seem haphazard or unpredictable because their movement is burst-like: quick, sharp, and erratic. Meanwhile, whales, who drift effortlessly through water, produce smooth, open-ended vocalizations that match their environment. Human music, though, follows the beat of our footsteps.
Music as a Journey
When listening to music, we embark on a journey. Our minds experience music not just as sounds but as a complex narrative, an unfolding story that starts at one place and moves to another. This is a deep echo from humanity’s ancient journey, possibly as far back as our migration out of Africa. We don’t just “hear” music—we follow it as if it were a path, an experience that taps into our evolutionary history.
The Brain’s Involvement in Music
Human music connects motion and sound through the wiring of our brains. The motor regions control movement, while the auditory cortex processes sound—an intersection that doesn’t exist the same way in other species. But it’s not just the motor cortex and auditory cortex at play. Your entire brain, layer by layer, engages with music in ways that range from basic reflexes to complex emotional processing.
Diving into Brain Layers
- Brainstem: At the brain’s deepest level, the brainstem reacts to unexpected sounds with reflexes. Loud bangs, for instance, trigger an instinctive response. This is the most primal level of our brain’s relationship with sound.
- Basal Ganglia: The next layer governs pleasure and rewards. The basal ganglia evaluate whether a sound is enjoyable or unpleasant.
- Amygdala: This layer is all about emotion. Whether the music makes you feel joy, sadness, or fear, the amygdala is where these feelings originate.
- Neocortex: Finally, the most advanced layer, the neocortex, decodes patterns and structure. The same part of your brain that processes complex ideas also untangles the intricacies of a symphony or jazz piece.
Auditory Scene Analysis
Our ability to separate sounds in a noisy environment, like distinguishing one conversation at a crowded party, is thanks to something called “auditory scene analysis.” You may also know it as the “cocktail party effect.” Humans can tune into specific sounds even when surrounded by background noise. It’s how we can pick out a single melody line in a complex piece of music or identify the voice of someone we know in a crowded room. Birds, like penguins, share a similar ability: Emperor penguins can hear their mate’s call amidst tens of thousands of other nesting pairs.
This remarkable skill lets us enjoy and engage deeply with music, even in noisy environments.
Social and Mental Health Benefits of Music
Music offers so much more than entertainment or stress relief. It connects us. The greatest threat to our mental health is loneliness; music combats this by creating a social experience. Even listening by yourself taps into a shared cultural experience.
Research shows that music reduces cortisol, the stress hormone, and triggers the release of dopamine, a neurotransmitter associated with pleasure. Think of those songs that are etched in your memory—they’re markers of your past. Your first concert, your favorite childhood song, or the tunes that spoke to you during difficult times. Music allows us to express emotions beyond words. Its precision delivers what plain language can’t—communicating parts of our identity and memories.
The act of listening to music is like peeking into your mind’s mirror. You hear not just the notes but also your own emotions and history.
The Active Role of Listening to Music
Many of us think of listening to music as a passive activity. But that couldn’t be further from the truth. Hearing music fully engages the brain, turning listening into a highly active, creative process. Music pulls us into the moment, offering a form of mindfulness and contemplation.
When a song triggers intense emotions, it’s not just relaxing. It’s a dynamic processing effort, one that brings rich layers of thought and memory into the present moment. Compared to meditation or other mindfulness practices, music offers a multi-faceted route to being fully present.
Development of Rhythm and Mirror Neurons
Humans are naturally wired to imitate rhythm, and this starts early. Children quickly learn to replicate simple melodies or beats because of mirror neurons. These neurons let you “feel” what you see someone else do—it’s why watching another person yawn makes you yawn too. The same reaction happens when you hear a melody. Without even tapping your fingers, your brain mirrors the rhythm.
Mimesis in Human Behavior
Mirror neurons, however, don’t stop at physical mimicry. They also play into our emotional world. When we hear a slow, soulful song filled with sadness, we feel sad—not just from the melody but from our brain’s mimicry of the emotional cues embedded in the music. This interplay of sound and emotion feeds off a deep instinctive behavior known as mimesis—our natural tendency to imitate and mirror the world around us.
Emotion’s Role in Survival
It’s important to remember that emotions aren’t just feelings. They’re responses geared toward survival. Happiness occurs when we accomplish something significant. Anger rises when our goals are blocked. Sadness is tied to loss, and fear prepares us for fight or flight.
Music taps into these same responses. Some compositions can evoke a visceral reaction known as “the chills”—a physical response where you feel goosebumps. This is similar to how your body would react to fear, yet, in music, it offers a safe space to experience these intense moments without the threat.
Music as Mental Time Travel
Listening to music pulls us through layers of consciousness. At one level, it’s pure pleasure. At another, it’s memory, taking you back to a significant moment in your life. As you engage with music, you journey through the deep levels of human experience, your brain wired to connect to a past you weren’t even aware of. Music becomes a powerful bridge to your evolutionary, emotional, and social past.
Conclusion
From its ancient beginnings with the rhythm of footsteps to its complex role in modern mental health, music is woven through every part of what it means to be human. It connects us to deeper biological rhythms, shapes our emotions, and offers a way to experience safe intensity. The science behind background music isn’t just about mood and behavior—it’s a testament to the profound ways soundtracks have shaped, and continue to shape, the human experience.
