This article examines the involvement of music in shaping people's gendered behavior in Dar es Salaam, Tanzania. Using Judith Butler's theory of gender performativity and the associated concepts of gender normalization and regulatory regimes of gender, the article analyzes how selected songs play a role in regulating individuals' gendered behavior and disciplining individuals who disrupt societal gender norms. It argues that composers of these songs employ accumulated gender norms from their societies. It also illustrates how the rhetoric and practice of building and maintaining national culture participate in regulating gendered and sexual aspects of musical performance in contemporary Tanzania.
