This article examines the continued salience of sung protests in South Africa by investigating the adaptation of anti-apartheid freedom songs along with the emergence of new expressive forms in ongoing community mobilizations. Based on sixteen months of ethnographic research in Johannesburg, this article argues that freedom songs constitute a distinct register that is politically efficacious due to singing’s aesthetically embodied effects. Formative elements of antiphony, repetition, and rhythm constitute a musical practice that organizes protest gatherings, allows for democratic leadership, and fosters collective participation. These practices yield a plasticity in the songs that makes them adaptable to changing political circumstances.
