Yahoo Tuning Groups Ultimate Backup tuning about ratio to cent : RE: [tuning] The 79-tone qanun pitches

Dear ozan

Type nominator in one cell , denominator in another and in third cell your formula.

Subject: Re: [tuning] The 79-tone qanun pitches

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.

Dear ozan

1- You can do all these calculation in some columns and then hide them.

2- you can right click on desired column , go to format cell , numbering , fraction.

In such a way , excell convert each A/B to for example ( a 1/b ) which now you can calculate to cent.

In these 2 ways you can have your column of A/B and columns of your calculations which are hide.

I could, but I don't want to do that. Is there no other way?

But you see, I wish to be able to modify the fractions in the column in question on demand, to evaluate if other ratios are approximated to my liking as well. Why won't Excel divide 81 by 80 when I give the link in the adjacent cell for calculating cent values? I want the program to produce the real numbers for the fraction I type in one column in the other column.

Or maybe I should copy the column containing the ratios to a hidden column that converts them to real numbers first? Maybe that might work...

Cordially,
Oz.
