The present work aims to further clarify the positive effect of vocal music on individuals, i.e, to identify certain fields in which there is an obvious improvement on mental health and overall well-being, before and after having experienced choral singing. In particular, there is examined the gain of self-esteem, as well as its social aspect in adolescents, who participate in a choir. Thus, this research may contribute to the current knowledge of the degree to which the performing art of choral singing may enhance self-esteem, overall wellbeing and sociability. Making the connections between singing and wellbeing can effectively promote better mental health and inclusivity, as it will encourage pupils to evolve into their better selves. The outcome of the present research may also help the target-school, since an effective collaboration between school, family and community (through several planned choir performances) is an important factor in the development of adolescents.
