GENEVAN 84 first appeared in the 1562 edition of the Genevan Psalter; Howard Slenk (PHH 3) harmonized it in 1985. The rhythm of the first phrase is altered to match that of the second and final phrase. (The original first phrase began with two half notes followed by four quarter notes.) This loved Genevan psalm features much rhythmic vitality and should be sung with firm organ accompaniment that inspires confident singing.
