The 79-tone qanun pitches

Hi Ozan.

Can you tell me what you would prefer to choose as a starting octave? For
the case I wanted to examine beat rates in your tuning and make an usable
whole of it all, I have to start with some absolute frequencies whose ratio,
in the best case, is 2/1.
And then, how much do you allow me to alter the starting frequency in case I
needed to find meaningful beat rates? For example, if I make a 12-tone
keyboard tuning whose A4 should be 440Hz at best, I know I should not change
this by more than, let's say, 10 cents.

Dear Petr, sorry for the late reply. I was working on an Excel worksheet
regarding my 79-tone scheme that might facilitate beat-rate calculations if
developed further. I couldn't manage to complete the ratios section though,
as the program refuses to calculate the cents for the numbers linked to the
fractions in the adjacent cell. (That is to say, e. g. 81/80 resides in cell
number G110, and yet, I cannot obtain the cent values for 81/80 when I use
the cell number instead of typing the ratio directly.) Perhaps someone here
knows a workaround solution?

Anyway, I wonder if it is possible to make all the tempered 5ths
equal-beating. But I surmise that would require drastic alterations.
Instead, maybe we can focus on integer beat-rates. For starters, we could
consider 1/1 to be 260 Hz. It could be allowed to alter this reference tone
5 cents up or down.

Do you think we can make progress?

Cordially,
Oz.

Hi Ozan.

I'm very sorry for not informing you sooner, or more precisely, not having
an idea of having to inform you sooner, that I have some sort of "reduced"
version of WinXP. As a result, I have to sincerely regret your time as I
don't use Excel. I know it sounds strange; but that's the way it is. If I
knew I should have told you, I would, of course.
Anyway, thanks for your references. I'll try to think about that a bit. In
the end, maybe I'll go for another starting octave than the degrees 0 and
79, who knows? When I was making the beat rate scheme for the 2/7-comma
meantone, I finally chose to start with degrees 9 and -3 (i.e. A4 and A3)
though the scale itself was made to start at C. It's just because this is a
more convenient way for my purposes as there are quite a lot of tuning forks
tuned to A4. I don't know what the situation is like at yours as far as
tuning forks or other tuning devices are concerned; but if you think you can
find a C4 or a C5 easily somewhere, then there's no problem to start with
the actual 1/1. I'm leaving the decision on you.

Petr, no worries there my colleague. Mayhap you can view the Excel file from
another computer? I think it will be well worth the effort.

All in all, I have discovered that tempering the second fifth in the cycle
by 19/53 of a syntonic comma (if not 79 MOS 159-tET) is practically
identical to 33 equal divisions of 4/3 carried over to the 79th degree which
then is completed to the octave whereby the `remainder comma` is moved
between steps 45-46....

I myself consider that the 59th degree (tempered 27/16) best corresponds to
A4=440 hz. By all means, use this standard if it better suits our intent.

Cordially,
Ozan

A version of WinXP that doesn't run Excel? That is
reduced!

Not that I don't run Excel, rather that I don't have it.
