Joe,

Mr. Dimitrov replied already to your question. Indeed, the tuning-system
proposed by Serge Cordier abandons the perfect octave. The name Cordier
didn't come up so much on the tuning-list until now, I think. By coincidence
I was confronted with his tuning, while visiting and working with two
professional singers in the Paris region. They had their piano tuned by Mr.
Cordier himself (he is working professionally as a piano-tuner in France)
and they both were very satisfied with the result, and they are no
microtonalists.

Cordier's temperament is called TEQJ ('tempérament égal à quintes justes)
and should not be confounded with the Pythagorean temperament. Cordier
splits up the perfect fifth in 7 equal parts to find his semi-tones (so the
7th root of 1.5) and accepts that every new octave will be a 1/7th
Pythagorean comma wide! So every 3/2 is perfect but only this interval and
not the 3/1 or the 4/3.

As a piano-tuning this makes sense, since the phenomena of inharmonicity
demands larger octaves if they want to be perceived as just to the human
ear. (Paul, Ed, Carl, am I right about this?)

Interesting enough, Mr. Cordier published a book 'Le piano et la justesse
orchestrale'. I haven't red this book yet, but I can immediately imagine one
aspect: the tuning of all the strings in the orchestra, from double-bass to
violin, is based on a cumulation of perfect fifths. This array of fifths can
be found perfectly on the Cordier tuned piano. Mr. Dimitrov, is that true?
Or do the string-players in an orchestra still slightly temper their open
string fifths to prevent especially the low C being too low?

After the equal division of the octave and the equal division of the fifth,
the next step could be the equal division of the major third into 4 steps
(4th root of 1.25) and simply forget about the octave as an imposing
interval.

Yes -- especially in the extreme registers.

I've seen the book and you're absolutely correct.

Watch out -- the octaves in this system would be 41 cents flat! Ouch!

Ouch!

I think it would make much more sense to take 5^(1/28) as basic; then
3/2 ~ 5^(1/4) is 5.4 cents flat and 2 ~ 5^(3/7) is 5.9 cents flat.

If we are seeking after the bizarre, we could tune to intervals
derived from zeros of the Riemann Zeta function on the critical line
in the hope that this might represent some condition of maximum
perversity. The tunings nearest the 12-et are 11.8226, 18 cents
sharp, and 12.2485, 25 cents flat.

Hello whit a large smile :)))

Because for the first time i see (between lot's of
e-mails) that you beguin to understand me !
I know about my horrible english, ok :)
But I will try to continue tha disscution.
First I would specify about the TEQJ...
I have the book of Mr Cordier before...1985 !
Now I dont approve the TEQJ...

Yes ! "My" octave is larger(2/1), my fifth is smaler
660 if the A=440 and i applie my consept when
according my violin and when I play also :))

The humain ear evaluate the hight frequency less than
the value physic and the bass sounds highter !

Not so perfects ;)) Because all musicians with the
instruments lice violoncells or contrabasses use
harmonics octaves when they verify yours strings !!!
And they accorde himselfs highter...

In theory only :) Is true that the fifhs "Cordier" are
larger than the fifths "Bach"...
Also today nobody accord the piano like...
It is not the solution, I mean !
For me the half tones are like the letters in the
alphabet-they must be free of engagements harmonic or
melodic out of any context musical...

Never :)) They according all the time...

Why evry time we must have one IMPOSING interval ?!
That's the question ;P

Stretched or expanded?
But attention ! Try with Cool Edit to hear no one but
6 expanded octaves-they sound not so beautifull...

If I can to append only this:
I think that we can abandon no only the octave but
also the fifth ect

Sorry ,

I dont see any problem if we dont use any perfect
interval(exept the unisson, sure)

This is true especially for sine waves. The more you have strong

No sir, that would only be 3.4 cents wide of a 2/1 octave.

10 cents wide would be a ratio of 2.0116.

Hi, Paul

When any violoncellist try to accord, he use the
octave
(the first harmonic) because it's easly to hear(the
register is highter), but this octave is perfect and
in the orchestral tunning (where we have the strings
in fifths) it's wrong to use this method. The result
is that the violoncell is too hight tuned...
