The Sacred Harp, a tunebook that first appeared in 1844, has stood as a model of early American musical culture for most of this century. Tunebooks such as this, printed in shape notes for public singing and singing schools, followed the New England tradition of singing hymns and Psalms from printed music. Nineteeth-century Americans were inundated by such books, but only the popularity of The Sacred Harp has endured throughout the twentieth century. With this tunebook as his focus, John Bealle surveys definitive moments in American musical history, from the lively singing schools of the New England Puritans to the dramatic theological crises that split New England Congregationalism, from the rise of the genteel urban mainstream in frontier Cincinnati to the bold "New South" movement that sought to transform the southern economy, from the nostalgic culture-writing era of the Great Depression to the post-World War II folksong revival. Although Bealle finds that much has changed in the last century, the custodians of the tradition of Sacred Harp singing have kept it alive and accessible in an increasingly diverse cultural marketplace. Public Worship, Private Faith is a thorough and readable analysis of the historical, social, musical, theological, and textual factors that have contributed to the endurance of Sacred Harp singing.

Christian scholars write to inspire renewed interest in actively praying, reciting, and singing the Psalms in personal and corporate times of worship, citing its biblical basis and historical emphasis.
