We - the Psalterium Foundation in The Netherlands - recorded the whole Psalter in Gregoriian Chant using the Nova Vulgata from2012-2018.. We even published these psalms and the Antiphons for each psalm in a separate book along with the CD-Box of12 CDs of all the recorded psalms with antiphons. We only include an acknowlegement on the first page of the book of online text source for the psalms - never asked any permission. No comments ever heard from Vatican publishers over copyright issues. See: ww.psalterium.nl. Why would or should they protest? We're just spreading the Good Word. The Church should be glad in all these ways to evangelizie the world.We are a not for profit Foundation under Dutch law. All proceeds go to new Gregorian chant projects. Our next edition?

"Lift up your heads, O gates" is supported by Jerome's translation of the Hebrew (4th c), and the Syriac (2nd c.). It's important to note that modern translations aren't simply taking the Masoretic text for granted but are performing textual criticism to find the best supported versions of the text.

The image is "a metaphoric expression for joyously welcoming God, pictured as a victorious king returning home to his palace" (Jewish Study Bible, NJPS translation). "[T]hey are like a council of elders, bowed down and anxious, awaiting the return of the army and the great warrior gone to battle." (NABRE)

For what it's worth, the Antiphonale Romanum I & II both list

Perhaps it is possible to inquire with the LEV about what permission is required.

@a_f_hawkins I suspect modern experts forget they are standing on the shoulders of giants. I also suspect that no one knows what manuscripts St Jerome had in his possession or had read. I think he may have had access to many manuscripts that no longer exist. I also find it VERY hard to believe that we have manuscripts from sources that St Jerome had no knowledge of...

Also I thought that the council of Trent demanded that WE accept that the Vulgate is the inerrant Word of God? So if the Vulgate is the errant Word of God, can the neo-vulgate also be a 'different' inerrant Word of God, or is it just a good translation?

The German bishops are insane (water is wet). But they should license it like ICEL does to those who come along in good faith to compose liturgical music. If you pay the fees and play ball, or at least try to play ball, they work with you, as far as I can tell. And they have fairly generous reproduction terms for individual Masses and the Divine Office or other rites. (Differences between the Romano-Germanic civil tradition and the common-law tradition of the Anglosphere don’t matter, I don’t think, in how generous they can be while retaining the copyright and asserting their rights as needed.)

I understand the impulse to use a (supposedly) more correct text, but the original text of the LXX wasn’t the Masoretic, and where the Vulgate departs from the latter somewhat significantly, the LXX also tends to do so, and I simply am astounded that anyone would wish to get caught up in using a copyrighted text when no one is going to object to using Jerome’s Vulgate, because it’s still the text and there are no legal issues surrounding it. Plus, and I’ll have to find the example, but the LXX and Vulgate readings that scholars tend to get upset about aren’t really improved in the NV; very, very, very few of the changed passages are truly made obscure in the Vulgate, and as for the example in ps 126 (I think it’s 126, and not 127), who cares, it’s the text that we received.

"Lift up your heads, O gates" is supported by Jerome's translation of the Hebrew (4th c), and the Syriac (2nd c.). It's important to note that modern translations aren't simply taking the Masoretic text for granted but are performing textual criticism to find the best supported versions of the text.

as perhaps the biggest fan in the Anglosphere of Winkworth’s translation of the German hymn sung in the closing weeks of Advent to FREYLINGHAUSEN (and not TRURO), I’m stuck with two translations from different sources (I would love to use said hymn for the Rorate Mass recessional!, putting the contrast into even greater relief), but all that the translation according to the Hebrew means that the Hebrew of Jerome’s day differed from the source of the LXX used to translate the psalter into Latin and that the Syriac tradition also reflected this, but who knows which reading is original. There’s also a tendency to assume that we maintained original readings when they match the post-Temple Hebrew tradition, when it could also be that people noticed discrepancies and then changed their own texts…or, if we wish to be more reserved, that both readings have always co-existed.

It's only inerrant in terms of faith and morals, not necessarily in terms of quality of translation in any other respect. "Princes" vs "heads" falls outside faith and morals.
