This work unveils the composition, the structure, the expansions, the tensions, asymmetries, fights and ways of political-professional recognization of workers' culture in Brazil, having as specificity, the musical language considered independent. The cultural work, the artistic creation activities and the technical and technologic process associated to it are in the center of the capitalism transformation in the last times, whose ambiguities integrate the new global chains of specialized symbolic services and the transnational industries. Behind the expansion of the global cultural markets, there is the creation of symbolic-economic value propitiated through the art and culture´s fieldwork. Looking at the professional category of art, through a work's parameter contributes to reveal the reality of an area that has not been studied that much: of the self-management artist. It is about not only considering the artistic activities as profession, but as paradigmatic expression of the current market. Analyzing the specifications that allows to draw the independent musician's morphology, collaborates for the theorical debate of the artistic work and the public cultural politics, in its fundamental articulations.
