LLANGLOFFAN is a Welsh carol or ballad tune, which appeared as a hymn tune in Llwybrau Moliant (The Paths of Praise). That collection of tunes for use by Baptists was edited by Lewis Jones and published in Wrexham in 1872. LLANGLOFFAN is named for a town in Glamorgan, Wales, at one time presumably the location of a church that honored St. Cloffan.

This is a sturdy tune in a minor key. You may wish to modulate after stanza 3 into the major form of this tune (LLANFYLLIN) and sing the final stanza in that bright major key.
