This paper explores the relationship of text and music in Dies Natalis by Gerald Finzi. Many of Gerald Finzi’s compositions have been researched and analyzed, but Dies Natalis, a work for high voice and string quartet, has received limited attention. The text is by Thomas Traherne, a lesser-known English poet and theologian. The research investigates textual interpretation and an explanation or a discussion of the religious mysticism of Traherne. After a biographical discussion of the composer and the poet, this paper provides a musical analysis, including a study of thematic and harmonic relationships in the work, and an examination of word painting and text setting. To facilitate my analysis, I used the piano reduction and not the string score for this project.
