In addition to two programmatic prefaces and words of praise, the work includes 82 songs, 74 of them devoted to key passages in the Old Testament (mostly from Prophets and Psalms), and eight related to apocryphal passages. The compositions were written by the organist Christian Flor, who was active at the St. Lamberti church in Lüneburg.
