it was all going swimmingly in part 2 until the end of bar 27, where a major seventh chord plops itself down squarely on an accented beat. surely something wrong there .. until that point it is wonderfully beautiful, and very different from part 1.

I don't mean to rely entirely on Chuck for interpretation, surely there are many here who are skilled in reading notation from Josquin's time ...

Attached below, CH Giffen 2011 edition; an alternate edition provided by CGM in the other josquin thread; the partbooks in order for Discantus, Altus, Tenor, and Bass (with the Altera Vox following tenor in canon). Part 2 begins on partbook pages 2 in each case; bars 25-28 are on the Giffen edition page 7. CGM's version fixes the problem (bar 70) by simply changing notes, not an ideal solution in my view.

In the tenor part, bar 25, a ligature is interpreted one way (and that way would have been very simply notated without a ligature), and in the same part, bar 28, the same ligature in a different place in the tempus is interpreted the same way (and again it could be simply notated without a ligature)?
