On composing for a brain that is always listening.

There is a sound I make before I compose.

Not a note. Not a melody. More like a settling — a slow exhale through the nose, a stillness that arrives in the hands before it reaches the mind. My body knows what’s about to happen before I do. It prepares. It waits.

For most of my life, I didn’t understand why music felt like more than pleasure. Why certain frequencies landed in my chest like something remembered. Why a particular rhythm could turn off the noise in my nervous system the way nothing else could — not sleep, not silence, not trying very hard to calm down.

It took me a long time to realize: my brain wasn’t just listening to music. It was using it.

The Brain That Won’t Stop Listening

A neurodivergent nervous system doesn’t take breaks from processing. Even in a quiet room, something is always being catalogued, filtered, flagged. The hum of the refrigerator. The texture of the air. The slight wrongness of a fluorescent bulb two rooms away.

Most people experience sound as background. I experience it as foreground. Always. The world is loud in ways that don’t show up on any decibel meter.

Which means that when I found sounds that helped — that actually quieted the internal static instead of adding to it — I held onto them the way you hold onto something precious. I replayed them. I studied them. I began, slowly, to reverse-engineer them.

What made this frequency different from that one? Why did rainfall in this recording soothe me when rainfall in that one felt irritating? Why did this rhythm help me think while that one fractured my attention into pieces?

I was asking scientific questions. I just didn’t know it yet.

Composing as a Form of Self-Study

When I began making music intentionally — not just playing, but designing — something shifted. I wasn’t composing for an audience. I was composing for one subject: myself.

I would start with a question. Can a whispered voice carrying factual information help me stay present when my mind is fragmenting? What happens to my body if I layer a heartbeat-like bass pulse beneath a solfeggio tone? If I build a rhythm that is complex but ultimately predictable, will my brain relax into it the way you relax into a familiar route home?

Then I would build the track. Then I would listen. Then I would write down what I noticed.

Over time, I began to trust what I was learning. Not because it matched the literature — though often it did — but because the consistency of the results became its own kind of evidence. The same frequencies kept doing the same things. The same structural choices kept producing the same states.

My body was telling me something true. I just had to be willing to listen as carefully as I compose.

What the Music Taught Me About My Own Mind

The most surprising thing I discovered wasn’t a frequency or a tempo. It was a pattern of self-knowledge.

When I composed music that helped me regulate, I was, in a very real sense, writing a map of my own nervous system. Each track became a diagram. This is where the anxiety lives. This is what calms it. This is the sound of my brain when it’s working the way it wants to work.

I began to understand that the chaos I’d spent years trying to manage wasn’t random. It had structure. It had preferences. It responded to things — reliably, consistently, intelligently. My nervous system wasn’t broken. It was just waiting for someone to pay attention to it on its own terms.

The music was a way of doing that. Of paying attention on my own terms.

You Don’t Have to Be a Musician

I want to say this clearly: you don’t need to compose to do what I’m describing.

You just need to notice. To pay attention to which sounds make you feel more like yourself and which ones pull you away from yourself. To treat your own responses as data worth collecting.

Start small. Pick one song that reliably shifts your state — calms the overload, sharpens the fog, returns you to your body. Listen to it the way a scientist might. What is it doing? Where do you feel it? What changes?

Write it down. That’s the experiment. That’s the sonic lab. That’s the beginning of understanding your own brain through the language it already speaks.

Because here’s what I know after years of composing for my own nervous system: the music was never separate from the mind that made it. Every track I’ve ever created has been, in some sense, a self-portrait.

The song you keep returning to? It’s trying to tell you something. It’s worth learning to hear it.
