This 90-minute roundtable extends from a research project at the intersections of neuropsychology and ethnomusicology. The project involved designing and executing data collection on musical rhythm and cognition in healthy aging adults. The project included creation and testing of audio recordings of musical rhythms, recordings which researchers interpreted differently depending on their disciplinary background. Members included two neuropsychologists and three ethnomusicologists, each of whom will participate in the roundtable. To the neuropsychologists, the recordings satisfied the criteria for “music,” but to the ethnomusicologists, they had a questionable status due to their lack of cultural context. These divergent perspectives highlight the purpose of this roundtable: to discuss the boundaries and definitions of music from varied disciplinary orientations. Presenters 1, an ethnomusicologist, will consider ethnography and cultural context in relation to our project. Presenter 2, also an ethnomusicologist, will consider mentorship in relation to design of our project. Presenters 3&4, both neuropsychologists, will discuss measurement of cognition and brain activity in relation to musical rhythm. By focusing on different methodological orientations to the study of musical rhythm, this roundtable will invite contemplation of the following questions: what counts as knowledge; what counts as evidence; how do we gather information; and how do we draw conclusions? Inspired by the work of Judith Becker (2004, 2009), we intend for conversation to zoom in and out of challenges present when designing and executing projects at the intersections of the humanities and sciences, encouraging curiosity into research designs perhaps misconstrued via limited awareness between disciplinary orientations.
