To make things easier for our congregation we always sing the Gloria from Mass VIII and Credo III (since we've had some dear old folks request it after we sang a new Gloria one Sunday) and that probably helps provide some continuity for them.
...we have embarked, with our priest's OK, on a project of eventually singing all 18 of these Masses. At a rate of 3 or 4 per year.
• Kyrie simplex Va
• Mozarabic Gloria
• Ambrosian Credo
• Ambrosian Sanctus or Sanctus XIII
• Agnus simplex Vb
I would align the movements of the Ordinary to a particular mode.
So, I take it there are no Mass settings in the Kyriale in which all the parts are in the same mode?
Another question: what would be the benefit of having all the parts in the same mode? Continuity? Seamlessness?
Are you accompanying the Ordinary or singing acapella? If you're accompanying the Ordinary, how can you know in advance what pitch the preface will end on? Would you have to accompany the Dominus vobiscum dialogue in order to give the priest the correct note to start the preface on? That's the only way I can think of to do it.
I don't have the necessary skill set to transpose on the spot or improvise an accompaniment. I remember watching my mother pick out the pitch very softly on the organ as the priest was singing and then transpose the accompaniment accordingly but I'm not at that level. (I could do it if you gave me a half an hour to prepare it, but not on the spot.)
Thank you for the link to Fortescue's notes! This is an invaluable resource and something to strive for and makes the Missa Cantata truly a musical work of art.
