This work is a study of the collective musical experience and its repercussions on the dynamics of the psyche as well as their ability to transform the suffering due to social injustice. The study is based on psychological assistance in the project Ação Social pela Música do Brasil - núcleo Dona Marta, a orchestra for children and teenagers from five different slums in the southern zone of Rio de Janeiro city. This project is associated to the National System of Children and Youth Orchestras of the State of Venezuela, El Sistema, whose teaching methodology has been internationally recognized for its integrative actions in groups considered most vulnerable socially. This work seeks to engage some subjects of psychoanalysis, musicology and sociology domains, with a focus on a possible link between the concept of Thalassic regression of Sàndor Ferenczi, creativity and transitional phenomena theorized by Donald Winnicott, and notions like tactics, profanation, cooperation and common, as proposed respectively by Michel de Certeau, Giorgio Agamben, Richard Sennett and François Jullien. In this articulation, the sound-sensory space receives an approximation with the potential space of culture and the music, in their common dimension, is understood as subjective and political resource, as astuteness or as arts of doing against suffering social.
