The first notes sound — and a familiar feeling arises: "I know this."
Sometimes the song's title comes to mind right away. Sometimes you already want to continue the melody, but the words haven't come yet. Music unfolds in time, and recognition gradually unfolds along with it.
How does the brain connect what we hear now with what is already stored in memory?
This is the subject of the work A trio of brain networks dynamically orchestrates music recognition — "Three interacting brain networks enable music recognition," published on 10 November 2026 on the bioRxiv platform. For now this is a preprint: the results have not yet undergone independent scientific peer review.
To hear, to remember, to recognize
A team of researchers, including Barbara Grosjean, Leonardo Bonetti and David Quiroga-Martinez, analyzed intracranial recordings of brain activity from 30 participants during the recognition of musical sequences. This method records electrical activity using electrodes inside the skull. The scientists studied high-frequency activity in the range of 70–160 hertz — this is a characteristic of the measured brain activity, not the frequency of the music being listened to.
The authors identified three interacting functional networks. One was associated with the processing of sound information, another with combining what was heard with memory and context, and the third with forming the decision about recognition.
The word "network" here means the joint work of brain regions. These are not three isolated centers with separate buttons for "listen," "remember" and "decide."
The picture proposed by the researchers is far more fluid: perception and memory exchange information as the melody plays.
Familiar music changes the very process of listening
During the recognition of memorized sequences, activity associated with the direct processing of sound gradually weakened. At the same time, sound information was combined with data from memory and the current context, while the activity of the decision-making network developed in the direction of preparing a response.
Novel sequences changed this organization: sensory responses persisted longer, and the dynamics of decision formation were different. The authors also discovered a bidirectional interaction between the perception and information-integration networks.
Put simply, familiarity with music influences how the brain continues to process it. What has already been heard creates a context for the sounds that follow.
Let us imagine a melody we remember well. Each new note arrives into a space of expectations: we already have some idea of what comes next. With an unfamiliar sequence, one has to follow the incoming sound more attentively. This is a vivid analogy that helps approach the research question, rather than a separate result of the experiment.
What the work says about memory — and what it does not yet say
The study is devoted to the recognition of musical sequences. It did not test how a song brings back memories of childhood, a loved one or a particular place.
These experiences are familiar to many listeners, yet it would be inaccurate to attribute their study to this work. Here the scientists examine a more specific process: how the brain matches unfolding sound with stored musical information..
In every encounter, music sounds anew
For the listener, this scientific story has a beautiful continuation.
We come to a familiar composition with our own experience. Today we notice the voice, tomorrow the movement of the bass, and another time our attention lingers on a pause. The recording may remain the same, while our encounter with it takes on new shades.
Here begins the space of personal experience, which is broader than the task of a particular experiment. Music becomes an occasion to listen closely: what resonates in me right now? Which detail previously went unnoticed? Do I want to sing along, move, or simply remain in silence after the last sound?
Everyone has the freedom of their own response. And this uniqueness makes listening together especially interesting: a single melody receives many readings.
A familiar song continues to reveal itself — because in every new encounter with it, we are present, alive and changing.
