In this article, we argue that the musical schooling of immigrant students could be seen as forming a healthy test for any educational context in terms of how democracy is enacted. We engage in a discussion linking music education, agency, pluralism and democracy. In our theoretical reconstruction of multicultural music education we first make a review on how music education literature has approached the cultural and musical schooling of immigrant students. We then attend to sociological theories to discuss why development of musical agency may be of particular importance to first generation immigrant students and how agency-enhancing music education may be connected to the development of sound democratic practices in the 21st century schooling.
