The environment affects people much more than it seems at first sight. It’s not just about ecology, food, physical activity. Experts believe that music can have an impact on the brain and play a role in different areas of life.

 

One of the most important discoveries of humanity is music. It is believed that it originated before the ancient people played with a stick a musical rhythm.

 

People hear music every day, it affects their emotional state and even the decisions made. Experts believe that musical rhythms affect the brain, and this fact should not be underestimated. This is the topic we want to dedicate today’s article to.

Sound and music

Sounds are waves that can spread in gases, liquid media, solids. The category of sounds that people hear most often is the vibrations of waves in gas, and thus in the air. When a sound wave reaches human ears, the eardrum reacts by vibrating. As a result, people hear different sounds, but not all. The hearing range is 20,000 – 20 Hz. Above is ultrasound, and below is infrasound.

 

For example, orcas, dolphins, and whales can hear ultrasound, due to which they can detect each other within 30 kilometers.

 

Many sounds that surround people are noise. It differs from music by a number of features. Noise vibrations are characterized by a continuous spectrum. Music is characterized by rhythmic and harmonious oscillations, which have a characteristic linear spectrum.

How does a melody relate to a hormonal background?

Experts believe that the sound of pleasant melodies is associated with the pleasure hormone – dopamine. It is also produced while eating delicious food and making love. If dopamine is not enough in the body, people may get depressed.

 

For information, an experiment was conducted with the participation of volunteers, who were to evaluate 60 tracks. In the course of the experiment, the scientists tracked the brain activity of the participants using MRI.

 

It turned out that the melodies that people like have a positive effect on the adjacent core and contribute to the production of dopamine. Therefore, when the mood is bad, it is desirable to listen to your favorite music. The researchers also concluded that music lessons have a positive impact on motor skills and ability to concentrate.

 

Noise and creativity

Scientists have proved that background low sounds promote creative activities and stimulate the right hemisphere of the brain. One of the characteristic examples of the positive impact of noise on creativity is the working environment of Ernest Hemingway. He preferred to work in cafes and similar places with background noise.

Melodies and sports

Training to your favorite music is not only pleasant, but also useful. The fact that the music can block the signals of the brain about physical fatigue. Another interesting nuance about training on bicycles. It turns out that people pedal faster to the fun music. Especially effective is the music, which has a rhythm of 145 beats per minute.

 

Music in psychology and medicine

Psychologists often resort to the use of music and sounds, noting its impact on the brain.

 

Recently, an experiment was conducted in which volunteers listened to melodies and evaluated facial expressions in images. It turned out that while listening to sad music, faces in the photo seemed sad, and when the music was playing, they seemed more fun. Scientists also noted cases when fun music irritated people with depression, and when sad music was playing it calmed them.

 

Musical motifs are also used in medicine. They favorably affect the ability to memorize information. Classical melodies, such as Mozart’s compositions, have a particularly positive effect.

Character and musical preferences

The experts found out that there is a connection between character and musical preferences.

 

    Rock and metal lovers are most often characterized by calm character and good mental health. But their self-esteem is often underestimated.

    Reggie prefers to listen to people who have high self-esteem.

    Fans of countryside are most often extroverts and like to communicate with people. At the same time, among them are often suicides.

 

The genre of music is not as important as to be liked. Pleasant tracks increase the hormone of joy and have a positive impact on creativity. However, unpleasant music will have the opposite effect.

 

In everyday life, people often underestimate the role of music, and it falls into the background. This trend can be seen, for example, in movies, cartoons, creative performances. Another 15 to 20 years ago, there was much more music in movies and cartoons than now.
