Back in 2004 I visited Rome and purchased (from a Vatican Bookstore) a Graduale Simplex and also a book of Mass Ordinary accompaniments. I can’t remember what it was called, I’ve got in my head ‘Lauda Sion’ but I may be wrong on that. Sadly I’ve lost the book (grrr!) but I took a copy of the Gloria for Mass VIII for use in my 'every' Sunday file. For a very amateur organist like me, the harmonies are both simple and effective and allow me sing whilst playing - not having a choir!
Please can anyone assist me with the name of the book and if it’s available online. It had a blue cover with a picture on and was in Italian (mainly). I know this is a long shot I know but I'm tapping into a wealth of knowledge here.
Not sure about the book you bought but an alternative could be the Liber Cantualis accompaniment. It's available from Solesmes and has Mass I, IV, VIII, IX, XI, XVII & XVIII plus Credos I & III - and a whole load of other stuff to boot. The accompaniments are very accessible. (It's blue, but there's no picture on the cover and it's in French - so 1 out of 3 criteria fulfilled). I've attached a scan of the contents.
I didn't know if it was appropriate to hijack a thread, but I thought I'd post a couple modern notation accompaniments of Mass XI's Sanctus and Agnus that I did for our assistant organist. I usually improvise accompaniments from the score, but I thought this would be a good exercise in humility! Hope these are helpful to some of you.
Obviously I intend them for free circulation, but please do credit me and say a prayer for me!
Very interesting. Thank you for sharing these. I confess that I wouldn't accompany either quite the way you do, but I think I recognize the same idea of "leading" the congregation, instead of confusing them -- or as I usually put it, thinking like a singer instead of like an instrumentalist or like a theory student.
These are unapologetically accompaniments to "gently guide" the congregation on a fairly substantial organ registration. Our accompaniments for the choir or scholae is most definitely of the Fontgombault variety. However, this is the American South, so congregational participation is very high: they sing with gusto, which can take some guidance. A more rhythmic accompaniment like this is, in my experience, necessary here, although they are certainly able to sing a cappella.
I'm not sure this relates to what you're looking for, but I have a copy of "Simplified Modal Accompaniment to the Vatican Kyriale and the Requiem Mass" by Dr. Eugene Lapierre.
It's identified as G-656 from the Gregorian Institute of America and copyright 1946
It's spiral bound and has a blue cover but no picture. (I was looking for the Jubilate Deo accompaniment that Chonak mentioned, but I have not yet found it.)
/5/s can be found even in the Solesmes Liber cantualis comitante, and I've later caught them in accompaniments I wrote myself. They're hard to avoid when harmonizing chant, which I suppose is why the experts recommend using first and second inversion as much as possible.
