The Genevan Psalter was compiled over a number of years in the Swiss city of Geneva, a center of Protestant activity during the Reformation, in response to the teaching of John Calvin that communal singing of psalms in the vernacular language is a foundational aspect of church life.Schuler, Dr. Louis E. "Duck". "History of the Genevan Psalter – Part 1". Credenda/Agenda, vol.13, no.1 (2007). This contrasted with the prevailing Catholic practice at the time in which sacred texts were chanted in Latin by the clergy only. Calvinist musicians including Bourgeois supplied many new melodies and adapted others from sources both sacred and secular. The final version of this psalter was completed in 1562.Havergal, William Henry (1854). A history of the old hundredth psalm tune, with specimens. Mason Brothers. p. 13. Calvin intended the melodies to be sung in plainsong during church services, but harmonized versions were provided for singing at home.
