Margo tells us that "Likewise Guillaume Costeley (1570) describes a
system dividing the octave into 19 equal 'thirdtones,' almost exactly
equivalent to 1/3-comma meantone with pure 6:5 minor thirds." Also, on
Tonalsoft we find that Costeley allegedly used this system to compose
the chanson Seigneur Dieu ta pitié. Can anyone give citable references
for these statements?

It seems a paper was presented titled "19-tET in a Renaissance Chanson
by Guillaume Costeley", by Ralph Lorenz. I'll see if I can track him down.

He read it at one of the Microfest conferences in Pomona, CA,
in either 2000 or 2001. I attended, and have his paper somewhere.
Sorry, too busy right now to look for it.
