The current study sought to assess the progress and effectiveness of a partnership program between a university and two high school drumming ensembles. A total of 32 students enrolled in world drumming courses in two urban high schools (n[subscript 1] = 16, n[subscript 2] = 16) participated in the study. An assessment tool was developed and administered before and after a 1-week residency of a professional music group that specialized in Brazilian music. Participant responses indicated a statistically significant difference in students' value perceptions as well as their willingness to recommend the world drumming class to other students. Although students enrolled in the younger world drumming group had higher score gains, students in the older group reported higher scores overall. Analysis of qualitative data indicated that students who participated for a longer period of time in the partnership were more proficient when articulating in writing why they value Brazilian music and its relationships to their own musical traditions.
