Keyboard temperament from the title page of Bach's "Das wohltemperirte Clavier" (1722).
The step-by-step explanation here shows how it is derived. Two full-length performances on harpsichord are included: Bach's C major and B major preludes from this book.
Research by Bradley Lehman, 2004, continuing a doctoral project from 1993-4 in "modified meantone" tuning as applied to Bach's music. The interpretation is based on analysis of Bach's extant keyboard music, plus a historical study of tuning methods, plus (in 2004) the suspiciously irregular drawing on Bach's title page.
This research was first published in an _Early Music_ (Oxford University Press journal) article, February-May 2005. Two printed portions and five web files comprise that article.

See http://www-personal.umich.edu/~bpl/larips/art.html for an article similar to this video demonstration: explaining how the C major and B major scales are blended together to derive all 12 notes of the chromatic scale, and tuned in this manner.
The academic articles are freely downloadable from http://www-personal.umich.edu/~bpl/larips/outline.html
and CD recordings are available as well:

The two recordings heard here are from the CD "Playing From Bach's Fancy":

I need more information on this "nudge" concept. Does it go to eleven? Ever? Or do you have to adjust your nudge whether it be a European or African nudge? Does it work for banjo?

@iluvspam6 The banjo has to really want to change.

@delameu Do you have hard evidence of any particular temperament on the Arnstadt organ, Werckmeister or otherwise? I have not heard of any.
