Yesterday was 18th Sunday after Pentecost - so we sang the Alleluia Timebunt gentes. Generally we sing from the Liber as it has the advantage of all mass parts in one book.
But I am trying to inform my singing by reading the GN.
I am not able to follow all the discussion that has taken place on the GN here but have found nothing that addresses this Alleluia.
Why do I find mode 1 starting on re in LU and mode 3 starting on mi in the GN??
And the GN has sharps!!
but i think i prefer the mode3.
pardon my french
