Mogens Pedersøn was a pupil of Melchior Borchgrevinck, later royal kapellmeister, and in 1619 he became royal vice kapellmeister. His major work, Pratum Spirituale ("Spiritual Pasture"), was published in Copenhagen in 1620, containing 21 five-part hymns and a mass, three motets, and a number of responsories. The works directly reflect the church-musical requirements of the time, which made available in print some kind of offerings for ultimately all situations of Lutheran culture.

In addition to the hymns that were part of the core liturgical program for the three feasts (Christmas, Easter, and Pentecost), there are Danish hymns, ten psalm hymns, and nine "free" hymns, partly from the distinctly Danish hymn tradition, partly from Luther's closest repertoire. The stylistic world that Pedersøn reveals in "Pratum Spirituale" is unquestionably only a very narrow segment of what this internationally experienced musician mastered: schooled between organ playing, Italian madrigal, Venetian double choir and English "consort music".
