I found the video of the funeral of the Empress Zita, Servant of God, on Youtube: https://www.youtube.com/watch?v=rBJrOIcW8H8

It's interesting to me, since it is such a public Mass. It might compare to our discussions of JFK's funeral. There are no rites at the opening, as far as I can tell: the body is neatly in place between the candles. Around the 16 minute mark, the Mass begins, and the announcer says, in German, that it is the Mozart. This was used at the Requiem Mass in Boston for JFK in 1964. (Alright, pardon the novel: I find it fascinating!)

The Kyrie is sung following the Introit. , that's clearly impermissible nowadays, and I suspect it was probably so in 1989, but the work would be disrupted by the split, which was not necessary in the traditional form. The Sequence shows up after the 1st reading.

The use of German is jarring, given that the Habsburgs are certainly friends of the traditional Latin Mass. One of their more distant descendants was married in that form in D.C. to an American, and I know another Habsburg, currently Hungary's ambassador to the Holy See, keeps up with the ICRSS. (Sadly the head of the family is separated from his spouse...) Political realities probably did not permit the Requiem Mass...

While I realize that there is nothing binding in itself on the Novus Ordo when differences from the usus antiquior are allowed, it is interesting to me that the cardinal wore the pallium. My metropolitan archbishop (and Ordinary) wears it only when absolutely required. What times may it be worn nowadays? It was restricted in the older usage, and I cannot envision its usage at a Requiem Mass (the ins-and-out of the Novus Ordo Pontifical Mass are something of which I know little, given my preferences for the older form). I'm intrigued the deacon doesn't kneel for the blessing at the Gospel (something not in the Requiem Mass...), since the servers do for the incense (again not the in the Requiem); things like that are inconsistent. On the other hand, the cardinal said Mass not from the throne but what amounts to the faldstool, which was the more appropriate way to sing the Requiem (though using the crozier, something omitted generally at a Requiem Mass).

They incensed the altar but did nothing at the casket, as I noted, which is interesting given in the Requiem the altar wouldn't be incensed then, which is something that some celebrants (licitly or not) might carry over into the Novus Ordo, albeit unintentionally (i.e. they just don't wish to use incense then).

We're treated to the Alleluia we are used to from (ahem!) the Vespers of the Paschal Vigil, err... many a Mass in the new form.

The Gospel was sung in German, and not at the ambo; I think the GIRM now prohibits it. The sung Gospel to the north is one of the most impressive features of the TLM... and this is the only reading I recognize, the raising of Lazarus in the Requiem, and the deacon sang it well. The cardinal was a terrible administrator, and I'm not so sure how faithful he was to the church's teaching, but he looks like a bishop ought, only missing the old pontificals (tunicle, gloves, buskins, stockings, and ring). Except, they forgot his miter at the offertory...and taste went out the window with the plastic missal stand.

The solemn Dominus vobiscum is interesting... It would be the ferial tone in the old form. He has Germanic Latin pronunciation, but the chant is beautiful.... The splitting of the Sanctus is unsatisfying. The same at the preface goes for the Pater Noster. I cannot imagine why the ferial tone was cut, considering there are 3 tones... It's easier to learn than the other two, in my view. The Pax was not in the Requiem, but I appreciate that basically all European bishops give it in the old style.

Of course they knelt for Communion.

The change to the cope is traditional, and it was done at Archduke Otto's funeral too. The aspersion & censing without music is strange... and the crucifix and candles were not in the nave. You can spot some black birettas in the 8th video, which contains the famous entrance into the church.

In the 9th video, the Vienna Boys Choir sings something, which I cannot place for the life of me! (It's sad that I cannot remember the melody...)
