Hmmm...we're doing this, and my organist plays out of Bragers low...where Mass 13 is in C Dorian grumbleland. I'm making him do it in D, sent him a bunch of links, but I think he's transposing/improving. I should send him this one too.
Sometimes I like to open to a random chant and play around with it, and I was particularly pleased with what this one brought out so I wrote it down quick! Glad to know it might be of use somewhere.
Also, I didn't notate anything for it, and maybe your organist will do this automatically, but this is especially cool if the "agnus dei" measures are played on a single 8' with celeste, and then the following measures on another manual with another stop or two, minus celeste. The bass can be doubled an octave down, except on the agnus dei measures where its really out of place.
The 2nd agnus dei is legendary when done this way.
