Sometimes when I hear a certain song, a shiver will run up my spine, I found this so curious I cold emailed a neuroscientist to ask them what they thought was going on. He was kind enough to email me back, and told me this was something called parasthesias. Like a stray thread daring me to pull it, I started down the path trying to understand what it was exactly music did to nervous systems.

That’s what drew me to I Heard There Was a Secret Chord for this month’s book club. Daniel Levitin, a neuroscientist and working musician, spends the whole book making the case that music isn’t just entertainment layered on top of biology, it’s one of the oldest tools we have for regulating it.

Quick Take

Levitin’s core argument: music has been used as medicine across nearly every culture in human history, and modern neuroscience is finally catching up to explain why. Rhythm, melody, and sound move through the brain and body in ways that can ease pain, calm the nervous system, and support healing from trauma, depression, and neurodegenerative disease, not as a metaphor, but as a measurable physiological process.

Read this if: you’ve ever noticed a specific song shift your state faster than any amount of thinking could, or you’re curious about the actual mechanism behind why music therapy works, not just that it does.

Summary

Drawing on decades of research plus his own career as a musician, Levitin traces how music has functioned as medicine across cultures, from ancient healing rituals to modern clinical settings. He walks through the science of how rhythm and melody move through the auditory system into the brainstem and beyond, showing measurable effects on pain perception, mood, and the recovery process in conditions like Parkinson’s, Alzheimer’s, depression, and chronic pain. Along the way he interviews musicians and clinicians about why sound reaches people when other interventions can’t, and makes the case that music’s power to heal isn’t incidental, it’s built into how our nervous systems are wired to respond to rhythm and tone.

Where This Connects to the Work I Do

• Brainspotting sessions often use bilateral sound alongside the visual focus. Rhythm and tone reach the nervous system directly, the same pathway Levitin spends the book tracing.
• A lot of what gets stored from a difficult experience isn’t verbal, it’s sensory. Sound is one of the fastest ways back into that material, which is part of why a specific song can surface something a conversation never would.
• Regulation isn’t just a cognitive skill, it’s a felt, physiological state. Music is one of the most direct, evolutionarily old tools we have for shifting that state.

Key Takeaways

• Music’s effects on the brain and body are measurable, not just anecdotal. Rhythm and melody move through the same systems that regulate pain, mood, and stress response.
• Cultures across history independently arrived at using music as medicine, which suggests it’s tapping into something built into human physiology, not a modern trend.
• Sound reaches parts of the nervous system that language often can’t access directly, which is part of why it can support healing where talk alone stalls out.

Questions I might ask if this was an actual book club

1. Is there a specific song that reliably shifts my mood or state? What does that tell me about what my body responds to?
2. Have I ever used music intentionally to regulate, rather than just to enjoy it?
3. If sound reaches the nervous system faster than language does, where else in my life could I be leaning on it more?

If This Resonated

If you’ve ever felt music move something in you faster than talking about it ever could, that’s not a coincidence, and it’s part of why sound plays a role in the work I do.
