Ecologies of Resonance in Christian Musicking^ Rexplores a diverse range of Christian musical activity through the conceptual lens of resonance, a concept rooted in the physical, vibrational, and sonic realm that carries with it an expansive ability to simultaneously describe personal, social, and spiritual realities. In this book, Mark Porter proposes that attention to patterns of back-and-forth interaction that exist in and alongside sonic activity can help to understand the dynamics of religious musicking in new ways and, at the same time, can provide a means for bringing diverse traditions into conversation. The book focuses on different questions arising out of human experience in the moment of worship. What happens if we take the entry point of a human being experiencing certain patterns of (more than) sonic interaction with the world around them as a focus for exploration? What different ecologies of interaction can be encountered? What kinds of patterns can be traced through different Christian worshiping environments? And how do these operate across multiple dimensions of experience? Chapters covering ascetic sounding, noisy congregations, and Internet live-streaming, among others, serve to highlight the diverse ecologies of resonance that surround Christian musicking, suggesting the potential to develop new perspectives on devotional musical activity that focus not primarily on compositions or theological ideals but on changing patterns of interaction across multiple dimensions between individuals, spaces, communities, and God.
