Book excerpt: The South Korean percussion genre, samul nori, is a world phenomenon whose rhythmic form is the key to its popularity and mobility. Based on both ethnographic research and close formal analysis, author Katherine In-Young Lee focuses on the kinetic experience of samul nori, drawing out the concept of dynamism to show its historical, philosophical, and pedagogical dimensions. Breaking with traditional approaches to the study of world music that privilege political, economic, institutional, or ideological analytical frameworks, Lee argues that because rhythmic forms are experienced on a somatic level, they swiftly move beyond national boundaries and provide sites for cross-cultural interaction.
