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.
