Pardon, especially for the lateness of the comment, but I believe there in an incorrect note in the soprano line at the first verse, being the final note held at the end of the word "humilitatem".
Hi! well caught, I assume you mean the D sharp at around 0:39. This is actually a variation that's used in Bach's version of the magnificat BWV243a, in Eflat major. I decided to keep this particular note instead of the more obvious D natural because I think it fits the general vibe of humility and lowliness. You can hear this version for example here open.spotify.com/track/3pGZMZRkxmVUpxWOeHmjCX?si=309ed85df99643be
