Of course Douce Dame Jolie would be one of the more melismatic ones. Of course.
I picked a stress scheme based on my favorite already-written lines and on how I thought the first few lines of the Machaut went. The results are below.
Then I went home and consulted Mistress Linette de Gallardon's "Music for the Beginning Scadian Harper," which has a version of Douce Dame Jolie. Because I can't speak French, but I know that the stresses come on beats 1 and 3 in 4/4 time.
dou-CE da-ME jo-LI-e? Really? Like I said, I don't speak French, but I do have some Spanish and a teeny bit of Italian, and usually (in those romance languages) the accent comes on the penultimate syllable. I'd have thought DOU-ce DA-me jo-LI-e. Or is Machaut messing with the usual pronunciation and stress? (Or is this a matter of editorial placement of the bar lines? Mistress Linette references two works from the 1920s on Machaut... I wonder who selected the meter and mensural divisions. I should email her.)
Anyway, I couldn't have gotten farther from the stress pattern in the extant music if I'd tried.
I'm sufficiently pleased with the poem that I'm not inclined to monkey with it any further. Nothing says I have to use the extant music, after all. I may see what I can adapt/steal from it - I'm still more comfortable adhering closely to an actual period example than trying my hand at composing in a period style.
Chorus:
Blind King John falls in the fray
Twelve fair knights around him lay
But he will not die today
Ich dien I carry evermore
France's king, he rides away
At Crecy
[I may just willfully mispronounce this.]
Blind King John would go fore
Twelve brave knights around him stay
Horses grey
Chivalrous, valiant corps
Bridles all in fine array
'Round each other let them lay
Make a knot so all convey
Their king to thickest of the war
Blind King John...
One good blow he would relay
Foeman slay
Dip his bright sword in gore
Forth they go, without delay
Death to pay
Mocking fear, laughter roars
Neither their blind king nor they
Any lament or dismay
In that battle did betray.
King John slew knights of England four
Blind King John...
English knights this troop waylay
Horses neigh
[It's donkeys that bray, isn't it?]
John the brave fights no more
And, too, here, in Crecy's clay
Twelve men stay
Witness this, I implore
Chiv'ry's crown has died today
For this worthy foe I pray
Mem'ry his I keep alway
None like him will be, nor were before [Eh, the line starts unstress, I can subdivide a note...]
Blind King John...
