Hello all,

The Tonalsoft Encyclopedia has a new name and a new look:

Tonalsoft Encyclopedia of Microtonal Music Theory

http://tonalsoft.com/enc/

(You'll notice that the links which connect the
Encyclopedia pages with each other are temporarily gone
... not to worry, they'll be back soon.)

Dear Monz, I notice that there is no mention of a 78-cent tuning in your encyclopedia. Now, I find this to be an entertaining possibility that may deserve mention.

Cordially,
Ozan Yarman

Thanks for that info. I know nothing about any 78-cent
tuning ... if you've described it here before, i missed it.

Converting the Encyclopedia to the new format was a
major effort, which took about 4 times longer than i
thought it would (8 months, instead of my estimated
2 months) ... i'm basically finished with it for the
time being. There's a lot of work to do on Tonescape
to get it ready for the commercial release of version 1.0.

Send me some more info, and i'll make a page for it
when i get the time.

Dear Monz,

78-cent tuning is derived by equally dividing the fifth (702 cents) into 9 partitions. The results of this tuning are as follows:

78
156
234
312
390
468
546
624
702
780
858
936
1014
1092
1170

etc...

Alternatively, the scale can be created with a generator of 624 cents and a period of 1170 cents.

Note that you can achieve a modest 4:5:6 chord at every degree with such a tuning.

A Farey approximation with an order of 36 based on minimal differences yields the following results:

0: 1/1 0.000 unison, perfect prime
1: 23/22 76.956
2: 35/32 155.140 septimal neutral second
3: 8/7 231.174 septimal whole tone
4: 6/5 315.641 minor third
5: 5/4 386.314 major third
6: 38/29 467.936
7: 37/27 545.479
8: 43/30 623.249
9: 3/2 701.955 perfect fifth
10: 11/7 782.492 undecimal augmented fifth
11: 23/14 859.448
12: 55/32 937.632
13: 61/34 1011.929
14: 62/33 1091.763
15: 57/29 1169.891

The differences between these two scales are as follows:

1: 1: 1.044 cents 1.043595 0.1649 Hertz, 9.8956 cycles/min.
2: 2: 0.860 cents 0.860379 0.1422 Hertz, 8.5348 cycles/min.
3: 3: 2.826 cents 2.825906 0.4885 Hertz, 29.3076 cycles/min.
4: 4: -3.641 cents -3.641287 0.6596 Hertz, 39.5781 cycles/min.
5: 5: 3.686 cents 3.686286 0.6971 Hertz, 41.8251 cycles/min.
6: 6: 0.064 cents 0.064178 0.0127 Hertz, 0.7625 cycles/min.
7: 7: 0.521 cents 0.520963 0.1079 Hertz, 6.4742 cycles/min.
8: 8: 0.751 cents 0.751009 0.1627 Hertz, 9.7625 cycles/min.
9: 9: 0.045 cents 0.044999 0.0102 Hertz, 0.6120 cycles/min.
10: 10: -2.492 cents -2.492035 0.5914 Hertz, 35.4823 cycles/min.
11: 11: -1.448 cents -1.448440 0.3595 Hertz, 21.5672 cycles/min.
12: 12: -1.632 cents -1.631656 0.4236 Hertz, 25.4163 cycles/min.
13: 13: 2.071 cents 2.070604 0.5617 Hertz, 33.7042 cycles/min.
14: 14: 0.237 cents 0.237370 0.0674 Hertz, 4.0440 cycles/min.
15: 15: 0.109 cents 0.109177 0.0324 Hertz, 1.9458 cycles/min.
Mode: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
Total absolute difference : 21.4279 cents
Average absolute difference: 1.4285 cents
Root mean square difference: 1.8767 cents
Highest absolute difference: 3.6863 cents
Number of notes different: 15

Cordially,
Ozan

P.S. Good luck on your projects!

This is clearly closely related to the "valentine", or 31&46
temperament. 31edo gives us a generator of 2/31, or 77.4 cents, and
46edo of 3/46, or 78.3 cents. Anything in between can be counted as a
valentine generator, including 78 cents. 9/139 is a poptimal 7-limit
generator, and 17/262 9-limit, but 78/1200 = 13/200 certainly works
also. The notes you gave are the notes of the 16-note valentine MOS
using the 13/200 generator; it becomes a MOS if you assume you are
going to repeat the pattern in octaves.

I think if Monz puts up a page for this it should be in conjunction
with a valentine page.

I disagree. While Robert Valentine was largely interested in MOS
scales in an octave-repeating context, Wendy Carlos (like Ozan) was
interested in true non-octave equal tunings. Since her "Alpha" scale
is 78.0 cents/step, the scale Ozan brought up should be mentioned in
association with Wendy Carlos, not Robert Valentine.

Ozan,

You don't have to get very far through Monz's encyclopedia to come
across this entry:

http://tonalsoft.com/enc/a/alpha.aspx

There it is, a 78-cent (non-octave) equal tuning.

Best,
Paul

Ah yes, clumsy me. It was a naive thinking on my part where I imagined I had actually found something interesting that wasn't mentioned before.

Well, thank you for the reminder Paul. It's good to have you back in the tuning list!

The point clearly needs to be made when discussing a 78 cent scale
that if you stop at an octave and repeat, you get a 16 note MOS in a
known temperament. The same comment applies to 88 cent scales and 14
notes.
