About the piece
A prayer of protection that invokes the Trinity, the angels and Christ at every moment of life. This edition carries the melody with its text, in 113 measures in 3/4, with all the verses.
How to prepare it
It is a long piece of intermediate level. Its range is B♭3–D5 (a major tenth). The hard part is stamina: there are many verses, so share the effort (for example, alternating verses between the choir and the assembly). Rehearse the text in parts to memorize it well, and keep a slow, firm pulse that doesn't speed up toward the last verses.
When to use it
Sung in Ordinary Time, and traditional around the feast of Saint Patrick (March 17).
