mention 3 social function of a song

Answer:
1. To entertain a sad friend, we sing a song to entertain him, meaning the song has a social function

2.The song can make others more passionate and more confident with their abilities. For example, when someone follows a sporting event, the supporters always give the spirit through the song that is a national anthem.

3. The song can give the beauty and the memories for others. For example in weddings or birthday celebrations, sometimes songs can represent everything so they feel happy and comfortable, it means that a song has a social function in this case.
