SATB “Agnus Dei” after Fr. Gregorio Allegri (d. 1652)
published 13 July 2016 by Jeff Ostrowski

ORE THAN FIFTEEN YEARS AGO, while directing a small church choir, I adapted some chords from the MISERERE MEI falsobordone of Fr. Allegri, a Catholic priest who studied with Giovanni Bernardino Nanino. 1 This little adaptation has met with tremendous success over the years. Indeed, I’ve been astonished to find xerox copies in the most unexpected places!

The score, for anyone who wants it:

    * *  AGNUS DEI adapted from Rev’d Gregorio Allegri (d. 1652)

Were I to create such an adaptation today, I would probably do things differently—but I suppose that’s always how it goes, right?
