Renowned theologian and hymn writer, Brian Wren, explores here the theological significance of congregational singing, analyzes the importance of contemporary worship music, and explains the power of tune and text in the life and nurture of a congregation. Wren studies the lyrics of choruses, hymns, chants, and ritual songs, and identifies their importance as both poetry and communal utterances of theology. This is a valuable resource for church musicians, pastors, and other worship leaders.
