The source and target domain of this research project is situated at the crossroads of composition, performance and education. The idea of this investigation is to develop field research on the social projects I'm engaged in both in Brazil and in Belgium. I intend to perform, on a long-term basis, a series of compositions for the various ensembles present in these projects. The interaction with these contexts will help me to delve into the three key aspects of this research: my development as a composer by engaging in these different social projects, the impact my composition could have on students' perception and musical development, and finally how this process can help to build a bridge of communication between composer and the majority of society. Would it come precisely from the underprivileged strata of society, the answer to the current state of indifference of most people in society to contemporary music?
