Music and identity are inextricably linked. While a particular social or ethnic group's music may reflect characteristics of that group, it also functions in creating the identity of the group. In Andean Bolivia, the choloethnic group has very subjective and constantly changing boundaries. Cholo-ness is made possible through mediated cultural performances of all types, in which members actively choose elements from both criollo and Indian cultures. Music is one particularly effective way in which cholos create and maintain their identity. This thesis focuses on the ways in which cholos use music to create a hybrid identity in and around Cochabamba, Bolivia.
