Soft skills enable the individual to successfully face the problems and challenges of a complex society in flux and under constant uncertainty. Music, in its different forms of expression, is here introduced as an ideal tool for the development of intrapersonal and action skills such as adaptability, optimism and proactivity. In this paper we analyse a case study regarding a project carried out by and for future teachers. Our data collection methods included questionnaires, observations, student productions and interviews. The results reveal that music can be a mediating element for the development of soft skills. Specifically, it has been observed that music can help the individual to face and effectively resolve changing and novel situations that require self-efficacy, self-confidence and social support. Music can also improve the physical and socio-emotional well-being of individuals as well as helping them successfully face adversity.
