Sing The Feelings
Psychologically, every time a person sings it always gives him or her some level of personal satisfaction. Endorphins, the happy hormones are released. The effect is bigger when singing is done in front of a crowd. Confidence is built and it stays on for a long time. This helps the person have a more positive outlook in life as a whole. All of these are covered when a person sings within a group like a choir.
