Something about that certain power ballad makes you feel all the feelings. But what is it about the uplifting guitar solo that gives you the kind of chills typically reserved for the Grand Canyon or best man speeches that are a perfect mix of funny and touching? Turns out, music encourages a flow of dopamine to the same part of the brain that is activated by addiction, reward, or motivation. Since the brain is such a good listener, it can predict when the more uplifting part of the song is coming. Once the long-awaited chord hits, you’re in chill-city and it feels great. Even when the powerful movements occur in a sad song, research shows that the overall experience is still positive. Sadly, only about 50% of people feel chills when listening to music. Scientists found oddly specific evidence that the people most likely to experience chills are reward-driven and open to new experiences. So loosenup, man. You might feel something!
