Praise God, from whom all blessings flow;
Praise him, all creatures here below;
Praise him above, ye heav’nly host;
Praise Father, Son, and Holy Ghost.

Written By: Thomas Ken

Thomas Ken (July 1637 – 19 March 1711) was an English cleric who was considered the most eminent of the English non-juring bishops, and one of the fathers of modern English hymnology.

Music By: Louis Bourgeois, from Genfer Psalter

Loys “Louis” Bourgeois (c.1510–1560) was a French composer and music theorist of the Renaissance. He is most famous as one of the main compilers of Calvinist hymn tunes in the middle of the 16th century. One of the most famous melodies in all of Christendom, the Protestant doxology known as the Old 100th, is commonly attributed to him.

Louis Bourgeois is the one most responsible for the tunes in the Genevan Psalter, the source for the hymns of both the Reformed Church in England and the Pilgrims in America. In the original versions by Bourgeois, the music is monophonic, in accordance with the dictates of John Calvin, who disapproved not only of counterpoint but of any multiple parts; Bourgeois though did also provide four-part harmonizations, but they were reserved for singing and playing at home. Many of the four-part settings are syllabic and chordal, a style which has survived in many Protestant church services to the present day.

Of the tunes in the Genevan Psalter, some are reminiscent of secular chansons, others are directly borrowed from the Strasbourg Psalter; The remainder were composed by successivelyGuillaume Franc, Louis Bourgeois and Pierre Davantès. By far the most famous of Bourgeois’ compositions is the tune known as the Old 100th.
