The Isaac Nathan settings are at the very least charming and sometimes (as in 'We Sat Down and Wept) suggestive of dramatic expression, thanks for those Jaime.
I haven't had time to watch all of Kristin Hanson lecture yet and won't for several days but note insofar I have seen that she does still refer to the language having a basic 'binary-ternary' rhythmic basis (iambic-anapaestic drift, in my terms) while the discussion of the rising triple (our classical friend anapaest) seems to be concerned with the notion of a secondary beat along the the primary stress, which sounds like incipient Trager-Smith territory to me. But I have seen only about a quarter of the lecture yet.
And lots of other linguistic-prosodic goodies on the same channel it seems, thanks again Jaime.
