This Element contributes to the interdisciplinary study of mariachi, especially in the United States, by focusing on two areas that have yet to receive substantive academic attention: philanthropy and museum studies. In 2011, UNESCO included mariachi music on its list of expressions of intangible cultural heritage. While it is undoubtedly true that mariachi is in many ways intangible, this downplays expressions of its rich material culture and the work of scholars to research mariachi history beyond an emphasis on musical performance. The first section considers mariachi collecting and philanthropy in the US, especially the efforts of Edward E. Marsh and Chris Strachwitz. The second section examines the first major mariachi history museum/exhibit in the US, managed by the Mariachi Scholarship Foundation and housed at Southwestern College in California. Finally, some open areas for research are proposed and appendices concerning mariachi studies in the US are provided.
