Hello!
Composed this for my choir as an easier (and, alas, less sublime) alternative to the Allegri. Will be updating with recordings/subsequent drafts. Users of this forum have permission to print, perform, and record :)

Update: Some new edits, including a "descant" for the repetition of "Miserere Mei" at the end. I've been very pleased with how quickly our choir has picked this up.
