"Why fum'th in fight" is the third of nine psalm tunes composed by Thomas Tallis for Archbishop Matthew Parker's Psalter published in 1567. This melody, composed in the Phrygian mode, is historically significant as one of the first metrical psalm tunes published in English. Its enduring legacy was secured when Ralph Vaughan Williams used it as the foundation for his monumental "Fantasia on a Theme by Thomas Tallis" in 1910, transforming Tallis's simple but profound melody into a lush, romantic orchestral work that remains immensely popular today.
