another early enharmonicist

we've all heard of the 31-tone keyboards of vicentino, gonzaga,
stella, and colonna.

the other day i opened up the _companion to medieval and renaissance
music_ and saw mention of vito trasuntino's 1606 "clavemusicum
omnitonum" also with 31 tones. supposedly it was tuned by means of
a "tetrachord", like a monochord but with four strings.

according to this webpage:
http://music.cwru.edu/duffin/Vallotti/T1/55division.html
this is another example of 1/4-comma meantone extended to create a
nearly closed system.

anyone have any information on the "tetrachord"?

i found a picture here:

along with pictures of vicentino's archicembalo, which bears on the
current "meantone keyboards" discussion.

Possibly, it's only Vicentino, Colonna and Trasuntino I would have come up with.

No, but I saw a replica of Trasuntino's harpsichord in the Germanisches Museum, Nuremberg. It's one manual with lots of split keys.

***Is this the first time a picture of Vicentino's Archicembalo has
appeared on this list?? I don't remember seeing it before...
