Music therapy has a favourable effect on people suffering from mental disorders, providing benefits in areas such as self-esteem, self-realization and self-image, which are fundamental aspects of improving social skills and interpersonal relationships and will facilitate the process of social integration. It is important to work with this population and even more important to carry it out within a community context. After a bibliographic review and improved knowledge of the characteristics of this population, an intervention is proposed in the Arga Psychosocial Rehabilitation Center (CRPS Arga) in the San Juan/ Donibane neighbourhood (Pamplona). The main objective is the integration of these people into the community life of the neighbourhood, carrying out activities ranging from the most internal work, with the users in the centre itself, to external work, with a musical group formed by neighbours, to finally become an active part of the festive events and the social life of the neighbourhood. The evaluation was carried out using a record sheet and a Likert-type scale questionnaire. It can be affirmed that the development of the project contains all the necessary elements that will allow the execution of the proposed intervention.
