During World War II, a prolific Kiowa composer named Lewis Toyebo initiated a new choreo-musical genre called War Mother songs for the Kiowa War Mothers Chapter 18 as a means of encouragement while their sons deployed overseas. This article examines how these songs simultaneously evoke pre-reservation and post-reservation chronotopes of Kiowa martial motherhood. Through ethnographic research with Kiowa Elders, singers, War Mothers, and descendants of Kiowa composers, I analyze how War Mother songs express these chronotopes through musical (War Journey drumbeat), functional (preparing warriors for deployment and honoring returning veterans), and linguistic means (blending “Old Kiowa” and “Modern Kiowa”). Analysis of these chronotopes reveals how Kiowas creatively responded to settler colonialism to maintain gendered roles and personhoods that were important to their cultural identity. This article provides an ethnomusicological perspective on how chronotopes of gender are expressed through dynamic forms of music and dance.
