TERRA BEATA was originally a traditional English folk tune, a variant of which, entitled RUSPER, appeared in The English Hymnal in 1906. Franklin L. Sheppard (b. Philadelphia, PA, 1852; d. Germantown, PA, 1930) arranged the tune for Babcock's text and published it in the Presbyterian church school hymnal Alleluia (1915), edited by Sheppard (Babcock and Sheppard were friends).
After graduating from the University of Pennsylvania, Philadelphia, Sheppard entered the family foundry business in Baltimore, Maryland, in 1875. He was organist at Zion Episcopal Church and later was an elder and music director of the Second Presbyterian Church in Baltimore. President of the Presbyterian Board of Publications, Sheppard also served on the committee that prepared the Presbyterian Hymnal of 1911. In the history of hymnody he is remembered primarily for arranging the tune TERRA BEATA for “This Is My Father's World.”

TERRA BEATA (also called TERRA PATRIS) is Latin for "beautiful world." A lively melody with an extended range, the tune requires a light manner of performance as well as light accompaniment. Try using guitars and recorders. Harmony singing is fine as long as voices stay light and energetic. Organists, choose light and bright foundation stops, not heavy diapasons. Easily learned by children, this is a vivacious hymn that would be hampered by plodding or weightiness. Observe a ritard only on the last line of stanza 3.
