This guide offers explanatory notes and an introduction to hymn texts and tunes, accompanied by practical commentary on words and music to support congregational singing and worship leadership. Hymns are organized thematically—worship, God, Christ, the Holy Spirit, the Christian life, sacraments, church and family life, seasons, and special services—and include books for children, gospel songs, and a chorale section. A historical overview traces chorale origins, sources, and musical characteristics, noting influences from Lutheran, Bohemian, plainsong, and folk traditions and the role of prominent composers and harmonizations. The volume functions as a reference for planning services and understanding hymn heritage and usage.
