This work investigates the harmonic potential of the traditional Appalachian folk carol through a contemporary choral arrangement. Mack Wilberg, a composer and conductor known for his work with The Tabernacle Choir, utilizes his expertise in vocal arrangement to transform a simple folk melody into a complex SATB composition. The arrangement serves as both a musical interpretation of the nativity narrative and a technical exercise in choral dynamics and vocal layering.

Experts and choral directors frequently cite this arrangement as a standard selection for holiday repertoire due to its effective use of minor-key shifts. The score is noted for its accessibility to intermediate and advanced choirs while maintaining a high level of expressive quality.
