This volume investigates the musical potential of J.R.R. Tolkien's verse by pairing his Middle-earth poetry with original compositions by Donald Swann. The work serves as a collaborative exploration of how lyrical structure in fantasy literature can be translated into formal song cycles, utilizing Tolkien's own linguistic insights and Swann's melodic expertise to expand the reader's engagement with the legendarium. By providing both sheet music and scholarly commentary, the authors bridge the gap between literary text and performance art.

The work is regarded as a specialized companion piece for enthusiasts of Tolkien's linguistic and poetic output, offering a rare glimpse into the author's personal involvement in the musical adaptation of his work. Its inclusion of exclusive lore and unique annotations makes it a significant reference for those interested in the deeper structural elements of the Middle-earth legendarium.
