I'm working on a CD of solo Gregorian Chant to help fundraise for our new church. I'm concentrating on sequences as I enjoy the musical variation in them compared to the typical antiphon-verse chant, like Gloria Laus from Palm Sunday.

Amazon had a chant CD by Ars Gregoriana entitled Sequentia which contained Psallat Ecclesia - a sequence that I felt should fittingly be the title of the CD. I found a score which isn't quite the same as chanted on the CD. A little more digging and it appears the chant was composed by Nokter and an early MS has it in St Gallen notation - which is way beyond me.

However, a later St Gallen MS has it in more recognisable neumes.

I had found a score of Psallat Ecclesia in Musica Sacra's Summer 2007, Volume 134, Number 2 edition. Page 32. Online via Scribd. The chant is not quite as per the CD which more closely resembles that in the later St Gallen MS. The lyrics have a major difference too. At the end of v4 it is "diu" instead of "Domini" which changes the meaning of that verse. The CD booklet sadly has the comment "No authorised translation found by the editor".

Has anyone got an English translation of this please - apart from the translation as per the above Musica Sacra edition. Alternatively, could someone please tell me how "diu" changes the meaning of v4 from "Domini."

I've included Latin lyrics I found online that match the St Gallen MS. Helpfully, they contain the stress marks missing in the Musica Sacra score. I've interwoven the lyrics as helpfully translated in the Musica Sacra article by Clarence Zaar.

Psallat Ecclésia, mater illibáta et virgo sine ruga, honórem hujus Ecclésiæ!
Sing praises, Church, mother inviolate & virgin without wrinkle, to the honor of this temple.

Hæc domus áulæ cœléstis probátur partíceps,
This house is esteemed for sharing, with the celestial court,

In laude regis cœlórum et cerimóniis
in the praise and ceremony paid to the King of heaven.

Et lúmine contínuo æmúlans civitátem sine tenébris
And light continual, emulating the city without shadows.

Et córpora in grémio confóvens animárum quæ in Cœlo vivunt.
And cherishing in her bosom the bodies of souls that in heaven live.

Quam dextra protégat Dei ad laudem ípsius diu!
May God's right hand protect her, to the praise ???

Hic novam prolem grátia partúrit fœcúnda Spíritu Sancto
Here the new progeny of grace is born, made fruitful by the Holy Spirit.

Ángeli cives visítant hic suos et corpus súmitur Jesu.
Angels here visit their fellow citizens, and the body of Jesus is received,

Fúgiunt univérsa córpori nócua:
All that can harm the body flees;

Péreunt peccatrícis ánimæ crímina.
the guilt of the sinful soul is destroyed.

Hic vox lætítiæ persónat:
Here the voice of gladness resounds;

Hic pax et gáudia redúndant.
Here peace and joy overflow.

Hac domo Trinitáti laus et glória semper resúltant.
To the house of the Trinity, let honor and glory always resound.

Amen. Allelúja.

Thanks - John

PS Perhaps fortuitously, our parish's patron saint is St Francis of Assisi. Thomas de Celano composed several Franciscan sequences which I hope to include. However, a lot to learn - each is almost twice the length of Lauda Sion.

Also - apologies for a very long first post!
