Old 100th

Old 100th

"Old 100th" or "Old Hundredth" is a hymn tune in Long Metre from Pseaumes Octante Trois de David (1551) (the second edition of the Genevan Psalter) and is one of the best known melodies in all Christian musical traditions. The tune is usually attributed to the French composer Loys Bourgeois (c.1510 – c.1560).

Although the tune was first associated with Psalm 134 in the Genevan Psalter, the melody receives its current name from an association with the 100th Psalm, in a paraphrase by William Kethe entitled All People that on Earth do Dwell. The melody is commonly sung with diverse other lyrics as well.
