This article argues that conviviality (convivencia) is an alternative, performance-based epistemology that is enacted in the music and dance of the son jarocho from southern Veracruz, Mexico. In its traditional settings, son jarocho is played in a participatory musical celebration called a fandango. This article provides an ethnographic perspective of how marginalized musical communities of Veracruz enact an subaltern cosmopolitanism from below through an affective sociality encapsulated in of the fandango that has direct ramifications for how daily life is constructed in the region.
