I've been trying to figure this out, but there doesn't seem to be much of a ocnsensus bases on the missals I've looked at.
At a Missa Cantata, does one:
[LIST=1]stand at the prayer Orate fratres?
[LIST=2]kneel after the Sanctus or when it starts?
Did this vary from country to country (continent to continent)?
I don't believe it varies from place-to-place, but #1 can vary depending on the incensation. One stands when the congregation is incensed, and it often happens that that overlaps the Orate Fratres, and when it does, one is standing for that too. It also happens that the incensation overlaps the Secret, in which case one remains standing right through the Preface. (Personally, when I see that the incensation is taking long, I'll remain standing rather than do up-down gymnastics for all of 10 seconds.)
For #2, AFAIK, one kneels at the start of the Sanctus. :)
