Resonant Witness gathers together a wide, harmonious chorus of voices from across the musical and theological spectrum to show that music and theology can each learn much from the other - and that the majesty and power of both are profoundly amplified when they do. With essays touching on J. S. Bach, Hildegard of Bingen, Martin Luther, Karl Barth, Olivier Messiaen, jazz improvisation, South African freedom songs, and more, this volume encourages musicians and theologians to pursue a more fruitful and sustained engagement with one another.
