🐙Frisson

Have you ever been listening to a song and suddenly gotten goosebumps?

Not because you’re scared. Quite the opposite, it might happen during one of the most enjoyable moments of the entire song.

Maybe a new instrument suddenly comes in. The melody changes. The music builds toward a climax, or maybe a particular part is tied to a memory. Whatever the reason, a wave of chills can run through you, leaving you with goosebumps.

There’s actually a name for this experience: frisson, also known as aesthetic chills.
And the interesting part is that this isn’t just a fancy way of saying that something moved you deeply. Your body is genuinely having a physiological response

But why would music do that?

When we listen to music, our brains are constantly making predictions. And this isn’t unique to music, even as you’re reading this sentence, your brain is already making predictions about what word might come next.

When we hear a melody, after a few notes we can often start to anticipate where it’s going. Music can build up that expectation and then break it at just the right moment.

Maybe something unexpected enters the song, maybe the climax comes much later than we thought it would. This combination of expectation and surprise may be one reason certain moments in music feel so rewarding.

During these moments, the brain’s reward system can also become active, and dopamine release is associated with the experience of musical pleasure (Dopamine is everywhere)

why doesn’t everyone get this feeling from music?

People differ quite a lot in how prone they are to experiencing musical frisson.

And I’m saying musical frisson because frisson isn’t limited to music, it can also happen in response to other forms of art.

One person might get goosebumps from the same piece of music over and over again, while someone else might almost never experience that reaction.

One possible explanation is personality.
Research has found that people who score higher in the personality trait Openness to Experience tend to be more drawn to new experiences, imagination, beauty, art, and intellectual curiosity, and they also appear to be more prone to experiencing frisson.

But it’s not simply about liking art. Some brain-imaging research has found that people who frequently experience these reactions to music may have stronger structural connections between areas involved in auditory processing and regions involved in emotional and social processing

And sometimes, it isn’t really just the music.

The memories and emotions attached to a piece of music can make the reaction much stronger. That’s why the exact same song can affect two people in completely different ways.

For one person, it might just be a song.
For someone else, it might be a powerful trigger for a memory, an emotion, and eventually that familiar wave of goosebumps

But now we have a much newer piece of the puzzle.

In 2026, researchers analyzed data from more than 15,500 people to investigate whether differences in people’s tendency to experience frisson in response to music and art could also be related to genetic factors.

The results suggested that part of the variation between people may be associated with genetic and familial factors.

The researchers estimated that familial relatedness could account for up to about 29% of the variation in people’s proneness to experiencing aesthetic and musical chills. About one-quarter of that estimate was attributable to variation in common genetic markers known as SNPs.

But there’s a very important catch here. This does not mean that having a particular DNA sequence will make you get goosebumps whenever your favorite song comes on.

It simply suggests that genetic differences may be one of several factors contributing to why people respond differently, alongside personality, life experiences, environment, and other factors we still don’t fully understand

So the next time a song gives you goosebumps, what’s happening may be much more complicated than simply saying, “This song is really beautiful.”

How strongly that song affects you is shaped not just by the song itself, but by a combination of your brain, your personality, your life experiences, your environment, and even parts of your biology.

So, that little shiver down your spine might have a surprisingly complicated story behind it.
