A metrical psalter is a kind of Bible translation: a book containing a metrical translation of all or part of the Book of Psalms in vernacular poetry, meant to be sung as hymns in a church. Some metrical psalters include melodies or even harmonizations. The composition of metrical psalters was a large enterprise of the Protestant Reformation, especially in its Calvinist manifestation.
