I think people who sing well will be more likely to gain good popularity in daily interpersonal communication than those who are tone deaf. For example, a company has two new colleagues, one can sing well and the other can't sing. When introducing himself as a new employee of the company at the morning meeting, he sang a nice song to everyone after introducing himself, while the other party just introduced himself. Under such circumstances, perhaps all employees in the company will remember this new colleague who sings well, and even if they can't remember his name, they will be familiar with him. When they see him, they will remember that this is the person who sings a song. In contrast, another colleague's impression of him will be much blurred, because this feature may also be appreciated by company leaders. When the company has a literary performance, the first thing that people think of is that they can sing this song, and their position in the company will gradually rise. Not only that, a group of friends go to KTV to sing. If there are strange female friends, men who sing well are often more likely to win the favor of beautiful women. Maybe it's just because this wonderful singing attracted a girlfriend, so singing is still good.
