Thanks Carl for clarifying my comments, and threatening me with censorship.

At about 8 am GMT this morning when I attempted to follow the link intonationjuste, I got an 808 or 404 (unobtainable url)

I checked it again since I read your message and see that it does actually display now.

Hence my sarcasm, assumed the url to be either a spoof or a typo.

My best linguistic friend tells me that "with a pinch of salt" has a few different meanings:
1) Communications are of a comedic value.
2) Advice for which the integrity or credibility should be questioned.

I trust that you were using the term in the first sense.

I beg to disagree with your recommendation of 22 edo as a good fretting system for guitars.

Although it will produce some interesting intervals, they fail to be those that one would expect to find commonly in a 5L+2s pattern which has been used extensively in Western harmony.

More info. on this tuning and its harmonic potentials and limitations can be found at:

Count on it.

That's true. It's not the fretting to choose if you want to play
diatonic harmony. But I think it opens up more new worlds in fewer
tones than any other system.

Right, 22t-ET is in the Diaschismic family, IIRC. Of course, you are
familiar with Paul Erlich's Paper "Tonality, Temperament and Twenty-
two Tone Harmony" (22 is also interesting in that M22 is one of the
five Mathieu Groups, but more generally, has some interesting set-
theoretical properties. Oops there I go again...)

For example, 22 tone subsets have this interesting property with
their Z relations. These are when 2 or more set types have the same
interval vector. (A set type is a Tn/TnI type, which would be
a set, its transposes, and inverses, and their transposes).

Notice how the Z-related sets (Doubles, Triples, etc) have a
phenomenon of clustering in multiples of 5. I should get some
sort of award for the most obscure contribution to the understanding
of 22-tET! (11-sets include those with "normal" complementation
(always pairs) plus "strange" Z-relations)

22-ET supports (is a tuning of) diaschismic. It also supports
porcupine, pajara, and magic.
