Old 100th

"Old 100th" or "Old Hundredth" (also known as "Old Hundred") is a hymn tune in long metre, from the second edition of the Genevan Psalter. It is one of the best known melodies in many occidental Christian musical traditions. The tune is usually attributed to the French composer Louis 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 translation by William Kethe entitled "All People that on Earth do Dwell". The melody is also sung to various other lyrics, including the Common Doxology and various German Lutheran chorales. In that latter respect it was used by Johann Sebastian Bach as a cantus firmus in his chorale cantata Herr Gott, dich loben alle wir (BWV 130).
