Watch yourself while listening to your favorite music – your heart will probably beat faster, goosebumps will get on your skin and your palms will sweat a little. Agree, it's amazing how such an abstract phenomenon as music can evoke so many changes in the human body. Apparently, researchers from California have long been concerned with this phenomenon and decided to do a rather interesting experiment. Their goal is to find out which features of music have the greatest influence on the human body, and which areas of our body are influenced by the rhythm and mood of musical compositions.
To do the experiment, they needed a group of 40 volunteers. They let you listen to 3 songs that take 2 to 8 minutes. For the purity of the study, the songs were unfamiliar to the participants – if they included popular music, people could tie them to events in their lives that left them with some emotion. For example, if a song sounded in a dental clinic during tooth extraction, a person would immediately perceive it with a negative. When the tracks sounded for the first time, the volunteers were able to answer with pure soul, what emotions they cause of them. While listening to music, her brain was scanned by a magnetic resonance imaging device.
What happens to the body while listening to music?
In parallel, the researchers performed another experiment involving 60 volunteers. While listening to music, scientists monitored their heart rate and sweat gland activity. In addition, people were asked to rate their mood after listening to a song on a ten-point scale.
By the way, did you know that music can ease your pain?
The collected data was provided for processing by artificial intelligence. It turns out that the human body is particularly affected by the dynamics, the timbre, the rhythm and the number of instruments in the music played. For example, the human brain reacted sharply to the frequency and strength of the shock parts – listen to the song "Bad Romance" by Lady Gaga and know that the transversal temporal gyrus of your brain began to show a high level of activity.
It has also been found that the liveliest emotions of a person are caused by dynamic songs, in which the rhythm and timbre of the composition change within three minutes. That is, if someone hears monotonous Black Metal like the song "All shall fall" of the Norwegian band Immortal, he does not experience any sharp emotional outbursts. And while listening to Nirvana's legendary Smells Like Teen Spirit, you can experience much more emotion.
Another discovery was that a person's emotional response is also influenced by the number of instruments in the composition. The most negative effect on a person's mood is the music in G minor, with the saddest note in that key turning out to be sharp (F #). If there is a moment in the music composition when a new instrument is added and the volume is increased, the person most often wets their hands.

According to the researchers, their scientific work can help create playlists for the sport, focus on the work and do other daily activities. Such song lists are usually created by music service developers such as Apple Music and Spotify.
