Justice has been an urgent concern of twentieth-century hymn writers, but are they the first to place such an emphasis on it? In Let Justice Sing, Paul Westermeyer offers an answer with the hope that it will stimulate dialogue, future studies, and an understanding of the past that can be applied to the present. Let Justice Sing explores the content, context, and importance of justice within the warp and woof" of hymnody. By analyzing these aspects and past hymnic repertoires, it suggests to the Church and others who wish to join the moral deliberation it presumes, that not only have Christians always sung about justice, but the message transcends the messengers. The perspective and dialogue fostered by Let Justice Sing is directed to students in college or seminary courses where hymnody, Church music, or ethics is the topic; adults in forums or classes where questions about music and justice arise; and anyone with an interest in hymnody, justice, or the relationship between the two. Chapters are "Content: The Twentieth Century": "Content: Before the Twentieth Century, I"; "Content: Before the Twentieth Century, II"; "Context"; and "Hymnody and Justice." Paul Westermeyer, PhD, is Professor of Church Music at Luther Seminary, St. Paul, Minnesota. He teaches, directs music, and administers a master of sacred music degree program with St. Olaf College. His writing includes numerous articles and books. "
