Untersuchungen haben ergeben, dass das Hören von Musik mit einer anderen Person die Ähnlichkeit des subjektiven Vergnügens von Moment zu Moment erhöht und die neuronale Ausrichtung verbessert. Die Ergebnisse helfen zu erklären, wie Musik als wirkungsvolles Werkzeug für soziale Bindungen und kollektive emotionale Erfahrungen fungiert.

While sharing a musical experience with a friend might not drastically alter your overall enjoyment of a song, it tends to synchronize your brain activity and emotional responses. A recent study published in the journal Cortex has found that listening to music with another person increases the moment-to-moment similarity of subjective pleasure and enhances neural alignment. These findings help explain how music acts as a powerful tool for social bonding and collective emotional experiences

Human beings naturally use music as a social tool to connect with others. From singing lullabies to infants to gathering at large stadium concerts, music helps regulate emotions and foster a sense of group cohesion. The ability of music to align emotions and physical responses among audiences fulfills a basic human need for social connection.

Scientists recognize that both music and social interactions activate the brain’s reward centers. This shared activation suggests that the social setting in which people listen to music might alter the fundamental way the brain processes musical pleasure. The mesolimbic reward circuitry, a network in the brain responsible for feelings of intense pleasure, plays a major role in these experiences.

“We were interested in better understanding how sharing music influences both our emotions and our brain activity,” said study author Federico Curzel, a postdoctoral fellow at the University of Pavia, working with the Laboratory of Psychology of Aging and the MusiCognition lab. “Music is a powerful social tool that can promote bonding and a sense of togetherness, yet the underlying neural mechanisms of these shared experiences are still not well understood,” he explained.

Researchers found that sharing the listening experience increased what they called pleasure similarity within the pair. This means that as the song played, the two friends experienced rises and falls in their enjoyment at the exact same moments.

“Our findings suggest that when we share music with a friend, we don’t just listen together, we actually experience it more similarly,” Curzel explained. Even though the friends could not see each other’s rating sliders during the joint condition, “without talking or exchanging explicit feedbacks, their feelings of pleasure became aligned over time.”

Brain activity data revealed that listening to highly pleasurable music naturally boosted oxygen levels in the prefrontal cortex. An increase in oxygen indicates that a brain region is drawing more blood flow and working harder to process rewards.

Would make sense. I channel a lot of my emotions and find it best to express emotions through songs. Other people, me as well, relate music to certain experiences or memories. So when you listen to certain songs with people or share your music with them, I find it as a form of vulnerability. Although some times I don’t share all my music with people unless they’re really close.

It’s a very limited study because they based their conclusions on pairs of people who were already close friends who were allowed to choose their favorite music.
