How Music Literally Resonates with Our Brains: A New Theory
Have you ever experienced a profound connection with a song that goes beyond just listening? A new theory suggests that our bodies physically resonate with music, as our brain’s natural oscillations synchronize with elements like rhythm and pitch.
Music is often referred to as a ‘universal language’ because people from different cultures instinctively move to a beat. According to neural resonance theory, the reason certain musical elements sound pleasing to us is because they align with the resonant patterns in our brains.
Neuroscientist Caroline Palmer from McGill University in Canada explains, “This theory suggests that music is powerful not just because we hear it, but because our brains and bodies become it. This has significant implications for therapy, education, and technology.”
Over millennia, humans have honed musical sounds to what sounds best without necessarily understanding the scientific reasons behind it. Neural resonance theory (NRT) has now been formally described in a perspective paper by Palmer and her co-authors, reviewing the literature on musical neuroscience.
NRT suggests that neural oscillations synchronize with external audio at varying rates. Rhythm, on the slower end of the timescale, resonates with the beats in music that we can dance or drum along to. Neurons in the cortex oscillate at frequencies that align with these musical pulses.
Pitch, perceived at higher frequencies, is another key aspect. Gamma-frequency oscillations in the cortex sync with lower pitch ranges, while the auditory nerve and cochlea resonate with higher pitches.
These synchronized oscillations make music enjoyable for individuals across different musical backgrounds, from children to professional musicians. The authors of the paper explain, “Statistically universal structures may have arisen in music because they correspond to stable states of complex, pattern-forming dynamical systems.”
While there is a universal aspect to music appreciation, cultural influences play a role in shaping preferences for aspects like pulse and meter. The brain’s oscillations tend to align with learned structures over time, a process called attunement.
NRT also delves into the concept of groove, which is the irresistible urge to move to music. When a beat deviates slightly from a predictable pulse, the brain engages in nonlinear resonance to fill in the gaps. This phenomenon explains why certain music feels ‘groovy’ and conducive to dancing.
The paper explores how NRT sheds light on various aspects of music and human behavior, emphasizing the interconnectedness of the brain and body, music’s ability to convey emotion, and its role in interpersonal bonding and brain health.
The findings were published in the journal Nature Reviews Neuroscience, offering valuable insights into the profound impact music has on our minds and bodies.
