Music brings us great pleasure. Many can't imagine a day without listening to their favorite tunes. Each of us has our own musical preferences. Some are delighted with rock, others with classical music, some love jazz, and still others are drawn to folk songs. How does our brain determine how we perceive certain musical compositions? Why do we enjoy some music and not others?
Scientists have long been conducting research into the effects of music on the brain. It has been proven that when a person enjoys what they're listening to, the reward center is stimulated, improving brain function.
Listening to our favorite tunes stimulates the body to produce dopamine, the pleasure hormone. It's also produced when we eat delicious food or have sex. Any positive, enjoyable activity stimulates dopamine production.
Scientists working at the Montreal Neurological Institute conducted a music perception experiment involving nineteen volunteers aged 18 to 30. They were asked about their musical preferences and presented with sixty pieces of music to listen to. All the music presented was unfamiliar to the participants; they were hearing it for the first time.
Subjects were tasked with evaluating musical pieces by holding a sort of auction among them. They were required to pay a symbolic sum of money out of their own pocket for their favorite song. As a result, the scientists created an album of selected musical compositions for which the participants paid the most.
Each participant in the experiment was fitted with an MRI machine, which monitored their brain's response to the music they were listening to. Each track was 30 seconds long. This was enough time for the participant to confidently state whether they liked the tune or not.
While listening to music the subjects liked, activity was observed in several areas of their brain, including the so-called pleasure center. This activity was comparable to that seen during sex or alcohol consumption.
It takes the brain only a short time to determine whether a person likes a new melody . Then, its ability to anticipate expectations kicks in, and dopamine is released. A person experiences pleasure not only from the music, but also from the anticipation of the pleasure it is supposed to bring.
Scientists have found that listening to music triggers emotional associations in the human brain. Each musical composition evokes a specific emotion in us.
The more pleasant we find the sounds of a melody we hear, the more effectively new neural connections are formed, which underpin our cognitive abilities. These abilities enable us to interact with the environment: attention, perception, memory, logical thinking, imagination, and decision-making.
When a person listens to a certain combination of sounds that make up a melody, the areas of the brain responsible for pattern recognition, prediction, and emotional perception are activated. These areas of the brain interact with each other, resulting in aesthetic pleasure.
Let's not deny ourselves the pleasure of listening to our favorite song again. Enjoy the music and be happy!
