Music is closely related to human beings, who have been creating music since ancient times. Unconsciously humming a ditty, which is something we are used to, suddenly gets to the bottom of it, but it is difficult to answer. In my opinion, there are the following reasons why humans behave like this:

First, because music exists in our genes and in every life. Not only are there cells in our bodies that respond to music, but even a flower and a tree have a sense of music.

Farmers can grow better by listening to songs that match their frequency. The principle of humming a ditty when we are happy is similar to this.

I feel that sometimes when I hum a ditty, not only do I feel better, but my body naturally wants to move with the rhythm of my own humming ditty. There is such a program related to music in our brain. Have you noticed that we usually hum a song when we listen to it too much?

second, because human beings have the desire to express themselves. The reason why human beings can make sounds and speak is because they want to communicate and talk. Therefore, when a person has no one to talk to, he can't hold back, so he will communicate with himself and hum a tune to relieve himself.

Third, because music grows with us. We can perceive music before we are born. We will respond to the prenatal music played by our mother.

In our life, as long as we can hear it, sound is everywhere, and music is built on the basis of sound. If we can remember the sound, we can remember the music, because music is a beautiful sound.

In addition, human beings are creatures who know how to appreciate beauty, and they will be happy when they meet beautiful things. Therefore, when we are in a happy mood, we will want to take out the melody we know in our minds and add our own transformation to appreciate it, which will make us happier.

Many people like to hum songs while taking a bath. Presumably, it is because taking a bath relaxes the body and makes people feel happy physically and mentally. Even taking a bath wants rhythm. If there is rhythm, there must be accompaniment, so they hum. There are boys living downstairs in our dormitory, and a boy living in a dormitory at the lower right of us especially likes to hum songs in the bath, and it is an infinite single cycle. A song is sung over and over for two years until graduation (which is as good as the one who sings the flute in the corner of the playground every night in our school). Everyone who sings in four buildings can hear it, and people often complain, "Stop singing, it's terrible." However, people are immersed in their own songs and cannot extricate themselves.

If you are in a good mood, you can hum songs, but don't disturb people.
