The second octave of the third is made up by four such welltempered fifths c-g-d-a-e. The fifth e-b is perfect. From c descend six perfect fifths until g-flat (f-sharp) is reached, including octave transpositions where necessary, upon tuning a harpsichord. The chromatic scale wohltemperirt, ascending successively from c, reads in cent: """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" """"""""""""""""" The other problem is references. His comments appear to be assumptions without the backing of historical record or actual facts. The list of his writings is impressive. I would like to read "Das wohltemperirte Clavier" - Tuning and Musical Structure, EHM, 2/6 April 1980, 137-140. What is EHM? ---ric
