Adapting a tune written for Psalm 100 found in Wolff Köphel's Psalter (1538), Nicolai composed WIE SCHÖN LEUCHTET, which was published with the text in 1599. Although the tune was originally more varied rhythmically, the hymnal version here is isorhythmic (all equal rhythms) and set to the rich harmonization of Johann S. Bach (PHH 7). That setting will delight all choristers and challenge the organist's feet! Bach also used this tune in his cantatas 1, 36, 37, 61, and 172 and wrote a chorale prelude based on it (as have many other–especially Lutheran–composers).

A rounded bar form (AABA) tune, WIE SCHÖN LEUCHTET is a noble melody that has lost some of its strength due to isorhythm but has regained new color and vigor through the Bach harmonization. Try having the congregation sing this hymn in unison with harmony sung by the choir or played by brass instruments.
