GENEVAN 150 was first published in the 1562 edition of the Genevan Psalter. Dale Grotenhuis (PHH 4) harmonized the tune in 1985. Demonstrating how well they were in tune with the musical changes of the mid-sixteenth century, the Genevan musicians chose the Ionian mode (major) for this great doxology of the psalms. GENEVAN 150 is a majestic tune featuring some melodic repetitions and brisk rhythms. Like Psalm 149, this music requires joyful singing in parts and the participation of many instruments beyond full organ, but it should not be rushed.
