This chapter reimagines learning within the noise scene via situated learning theory and Communities of Practice (COPs) scholarship through the lens of the posthuman. To achieve this goal, I begin with an overview of extant COP literature before placing this scholarship in conversation with writings on posthumanism. I then return to literature on noise music to consider how noise music scenes embody the various components of COPs (or, more specifically, communities of musical practice). Finally, I return to posthuman theorizations of noise music to understand the posthuman manifestations of community building and maintenances within musical contexts. In doing so, I argue that noise music embraces the relational and structural elements of COPs, with community members shifting from peripheral participation to more substantial contributions over time, but does so through an ontological reimagining of membership. Rather than only considering individual people within the boundaries of community, noise music instead positions becoming entanglements of human and more-than-human contributors as community members that shape and maintain sociocultural spaces. I finish with an illustration of my arguments through an analysis of a performance by Instinct Control, mapping the matrix of relations and materials that construct posthuman forms of expression.
