That may simply be a matter of taste -- if you've read Nowitzky's page, as I
suggested, and read the posts of many musicians on this list, and read
Mathieu's book, you'll know that many truly _prefer_ their dominant sevenths
less than perfectly blending.

No I did not -- in fact, I believe that perfect singers would come close to
what a certain version of John deLaubenfels' dynamic tuning program does --
keep vertical chords in JI (except augmented triads, 6/9 chords, maybe
diminished sevenths . . .)

So, Jerry, what is your hypothesis on the "high third"?

Jerry, the same line of reasoning led many to argue (a few months back on
this list) that the ratios of 5 _had_ to be used for thirds and sixths in
early to middle Medieval times. I feel Margo Schulter and others made a
powerful case that the historical evidence indicates that these intervals
were compositionally used, and perceived, as _dissonant_. Dissonant ratios
are not ones whose ratios are perceived clearly. The only ratio-based guides
to their tuning would have been chains of relations by 2:3 or 3:4, operating
alongside certain cadential tendencies that may have biased major thirds and
sixths toward "expansion" and minor thirds and sixths toward "contraction".

Much as the thirds and sixths were unstable sonorities in early to late
Medieval times, the diminished fifth was an unstable sonority in Renaissance
through Classical times, and hence its tuning was likely inflenced quite
strongly by the 5:6|5:6 intervallic structure normally contained within it,
and also somewhat by the 3:4 relation existing between the "seventh of the
dominant" and the "tonic".

We need a historical reality check. Wolf, Schulter, et. al., did "common
practice," specifically the use of the tritone to define tonal keys, arise
as a result of flexible tuning or as a result of keyboards and lutes or some
combination of the two?
