The study examines the impacts of a project-based learning (PBL) methodology on the development of emotional skills involved in the learner’s individual and social well-being. This paper summarises the preliminary results of the case study in which the project ‘Opera as a Vehicle for Learning’ (LOVA) was implemented with a key stage 2 group in Mexico City. This project fostered the development of the students’ intra- and interpersonal skills, group decision-making, critical reasoning, active listening, oral and written expression and emotion sharing. Findings suggest that LOVA has proved to be a powerful methodological resource for the development of collaborative learning, emotional education and social interaction in groups. Findings also suggest that music learning can be used as a highly effective device for the development of social skills.
