Book excerpt: A well-known and respected authority on hymnody for more than forty years, Sing with Understanding is now available in its updated third edition. This edition builds on its predecessors' scholarship, and enhances it with recent developments. New to this edition is a focus on the theology of hymn texts and their music as they form Christians in prayer. More than one-hundred fifty congregational songs from the treasures of Western hymnody, recent Contemporary Christian repertoire, and the global church are analyzed in depth. Also new is a companion website featuring bibliographic resources for additional research, articles referenced in the print version, as well as a glossary of musical/theological terms and indexes.
