For anyone interested, here is my transcription of this music:

I like these pieces, because though they are organ versicles that "replace" the actual text of the Magnificat, they are 1) lyrical and 2) very short.

(In my opinion, this seems to put the organ and the actual human voices on more equal footing and in greater balance. It does not become an organ concert interrupted by Gregorian Chant!)

Tell me what you think!

EDIT: I express my gratitude to Mr. Allesio Cervelli, the organist in the YouTube recording, who graciously provided me with the original sheet music. This transcription exists for being more convenient to read from in some departments (eg being vertical rather than horizontal.)
