The number of Brazilian immigrants in the United States has greatly increased over the past three decades. In Phoenix, Arizona, this population increase reveals itself through a greater number of large Brazilian cultural events and higher demand for live Brazilian music. Music is so embedded in Brazilian culture that it serves as the ideal medium through which immigrants can reconnect to their Brazilian heritage. In this thesis, I contend that Brazilian immigrants in Phoenix, Arizona maintain their identity as Brazilians through various activities extracted from their home culture, the most prominent being musical interaction and participation. My research reveals three primary factors which form a foundation for maintaining cultural identity through music within the Brazilian immigrant community in Phoenix. These include the common experiences of immigration, diasporic identity, and the role of music within this diaspora. Music is one of the stronger art forms for representing emotions and creating an experience of relationship and connections. Music creates a medium with which to confirm identity, and makes the Brazilian immigrant population visible to other Americans and outsiders. While other Brazilian activities can also serve to maintain immigrants' identity, it is clear to me from five years of participant-observation that musical interaction and participation is the most prominent and effective means for Brazilians in Phoenix to maintain their cultural identity while living in the U.S. As a community, music unites the experiences of the Brazilian immigrants and removes them from the periphery of life in a new society.
