Guldberg's hymnal (published as Psalme-Bog eller En Samling af gamle og nye Psalmer 'Hymnal or A Collection of Old and New Hymns') is a hymnal that was created by Bishop Ludvig Harboe and Ove Høegh-Guldberg and was authorized for use in 1778.
[1][2] On behalf of King Christian VII of Denmark, Denmark's de facto prime minister, Ove Høegh-Guldberg, appointed a two-person committee, consisting of himself and the bishop of Zealand, Ludvig Harboe, to prepare a new hymnal.
[3] They sought to modernize Kingo's hymnal, primarily by removing the hymns that lacked the requisite "correctness, dignity, and strength" or whose poetic quality was too weak.
The hymnal was issued for the first time in 1778 and was printed in new editions in the following years.
It was authorized for use and adopted in Copenhagen in 1781 and in other towns in 1783; however, the powerful prime minister Guldberg was then forced to resign, and the introduction of the hymnal in rural areas was postponed.
