Why does music give us chills?

Music gives you chills because your brain is always betting on what comes next, and when a song bends or breaks that bet in just the right way, your reward system pays out. Emotion arises when something in the music, such as its rhythm or harmony, violates, delays or confirms what you expected. The tingle even has a name, frisson, French for "shiver", and its pleasure runs on dopamine, the brain's global reward signal, the same chemical that rises with food, sex and video games.

The idea is older than brain scanners. In 1956 the composer and philosopher Leonard Meyer published Emotion and Meaning in Music, arguing that music moves us by meeting and breaking our expectations. Labs now back him up: when the last chord of a four-chord progression is far more surprising than the three before it, listeners feel stronger sensations in the head, and in a 2019 study, drugs that raised or blocked dopamine turned the pleasure of music, chills included, up or down.

The shiver itself comes from your fight-or-flight wiring, the sympathetic nervous system. It can make tiny muscles at the base of each hair pull it upright, which is all a goose bump is. A frisson lasts only a few seconds and often rolls up your back as "shivers up the spine". Changes in harmony tend to bring shivers and goose bumps, while changes in melody are more likely to bring tears or a lump in the throat.
