Gb Db Ab Bb F. C. G. @ 3-lim
D.=1/1

Control the above output,
by summing up just that seven tempering-steps alltogether:

2*(|21 -13,-2 0 0,0 0 1> + |5 -4,4 0 0,-1 0 -1> + |12 -8,-4 1 1,1> )
+ |8 -3,4 -2 -2>

=|84 -53> =~-3.615...cents

collectively within Pythagorean 3-limit
all-in-all over the complete 53-cycle,
because all the 5-7-11-13-19-limit powers
do cancel out each others by the addition of the prime-vectors.
As a matter of course the integration of the corresponding
cent-values yield the same result.

Here comes an new rational cycle of 53 quintes.
That 'well'-temperature consists in 46 just pure 5ths of exactly 3/2.
Hence it includes barely seven remaining tempered 5ths,
in order to compensate the famous 'Mercator's-comma" |84 53>.
Follow the partition-pattern as excuted by the distribution-scheme
via two intermittent transitions into 19-limit intervals:

Now consider that verbose 53=46+7 cycle under closer look
in more concise representation for the 46 just pure 5ths:
Instead of that 46 just ones
examine and expand the 7 critical tempering-steps deeper en detail:

Start from unison 1/1=D.
A. E. B. F# C# D# A# @ 3-lim
|21 -13,-2 0 0,0 0 1> =~-0.529...cents 3==>19-lim bridge-comma

|12 -8,-4 1 1,1> =~-0.223...cents 11==>13-lim bridge-comma again
B- GB DB AB BB F\ @ 13-lim
|5 -4,4 0 0,-1 0 -1> =~-0.605...cents 13==>19-lim bridge-comma again
C\ G\ D\ A\ E\ B\ @ 19-lim
|21 -13,-2 0 0,0 0 1> =~-0.529...cents 19==>3-lim bridge-comma again
Gb Db Ab Bb F. C. G. @ 3-lim
D.=1/1 back home @ unison

Revise that approach:
Control again the total amount of output,
while roaming 5th-wise forwards through the whole tempering-process.
Perform that check by summing up over the seven deviation-steps
by stacking them alltogether at once over all the 7 "Monzo"s:

2*(|21 -13,-2 0 0,0 0 1> + |5 -4,4 0 0,-1 0 -1> + |12 -8,-4 1 1,1> )
+ |8 -3,4 -2 -2>

=|84 -53> =~-3.615...cents yields 'Mercator's-comma all-in-all.
Proof succesfully completed.

Result:
The 53 cirle compensates |84 -53> 'Mercator's-comma exactly.

For better reminding:
Study once more the above indicated 7 positions
where the seven-fold tempering acts:
Listen:
How do sound the 7 with-intend disturbed 5ths individually?
Locate that seven concerned 5ths concrete at the positions:

A#~F/ , E/~B/ , F+~C+ ,(E+=F-)~(B+=C-) E-~B- F\~C\ and B\~Gb

Against that 7 specific demanded deviations:
Insist in keeping all the other remaining 46 quintes just pure 3/2,
in order to conclude properly the complete 53=46+7 cycle,
without the least disturbance, as good as yours ears do allow.

Observation:
All the 7 bridges via the intermediate 5,7,11,13&19-limit powers,
do cancel out each others during the addition of the prime-vectors.
So we yield finally as sum |84 -53> over the whole 53 circle.
Consequently we got completely rid of all the intermediate occuring
higher limit powers

|m n> := |m n, ? ? ?, ? ? ?, ? ? ?>

except than the naturally remaining 3-limit |84 -53> M's-comma.

As a matter of course,
the integration of the corresponding cent-approximations
must yield the same result again...

2*(~0.529... +~0.605... +~0.223...) +~0.897... = ~3.611...cents

Self-evident only within the limitation of inherent rounding-errors,
that occurs here in the last decimal,
due to cut-off failure during the cent-conversion.

Excursion:
Compare that 7 amounts against the traditional 53-edo.
The 53-edo contains even more tiny tempering-deviations.
But that got distributed equally over all the 5ths uniformly:

~3.615...cents/53 = ~0.0682...cents @ each of the 53 quintes,
That's roughly about ~~1/15~~ of a single cent
@ each so smoothened 5th.

Reference reccomendation:

Quote:
"... |-84 53>, known as Mercator's comma or the 53-comma,
is a small comma of 3.615 cents which is the amount by which 53 fifths exceed 31 octaves..."

But please do not confuse my 53 ratios
with the more stupid or at least boring
http://en.wikipedia.org/wiki/53_equal_temperament
without any desirable 'key-characteristics'
http://biteyourownelbow.com/keychar.htm

But let's return back to the actual matter:
Now rearrange that chain of 53 pitches into up-wards ascending order:
Attend along that way as side-condition the constraint:
Locate them all mirror-inverted around the central unison=1/1 axis
in strictly consequent symmetric placement:

Especially regard an 'Scala'-specific side-note:
There in the 'scala'-reprensentation appears
the inherent mirror-symmetry again as the phenomenon:

Aa = Bb = Cc = Dd =.... = Yy = Zz = 2/1 = octave = @'

That characteristic octave-property
occurs exactly 26 := (53-1)/2 times,
when excluding the singular unison @=1/1
and its corresponding counterpart:
the octave @'=2/1
from the statistics of intervals,
to be omitted from counting, becasue considered as "implicit".

That pardigm can be found in the specification of the:
http://www.huygens-fokker.org/scala/scl_format.html
Quote from:
"The rules:...

* The second line contains the number of notes....
The lower limit is 0, which is possible since
degree 0 of 1/1 is implicit.

* The first note of 1/1 or 0.0 cents is implicit and not in the files.
"

Idea:
Restrict the whole 5ths-cycle completely within 5-limit ratios:

1/1=D. A. E. B. F# -schisma=|15 -8,-1>=~-1.95cents C# G# D# A# ...
...F+ C+ G+ D+ A+ E+=F- Monzisma=|54 -37,2>=~+0.29c B+=C- G- D- A-...
...Gb Db Ab Eb Bb -schisma=|15 -8,-1>=~-1.95cents F. C. G. D.=1/1

That got executed by 5-limit trisection of Mercator's-comma

|-84 53> = 2*(|-15 8,1>) -|54 -37,2> =~3.62...cents

More verbose en detail:

+-0 D. 1/1 unison

Remark:
That 53-cycle includes exactly the first attempt of
http://en.wikipedia.org/wiki/Kirnberger_temperament
as 12-out-of-53 dodecatonic subset:

A. E. B. F# -schisma C# G# D# A# F/ C/ G/ D/ 80/81=-SC A.

coincident at the same labeling of pitch-names.

Attend:
K1 contains inbetween the quinte: D/ and A.
an ugly syntonic 'wolf'-5th of
40/27 = (3/2)%(81/80) =~680.4...cents
that most tuners consider as unacceptable.

Agreed Gene,

let's overrun 11-limit,
so that even the next higher 13-limit 'flavor'
got included in order to enrich an meliorate 53-cycle:

Attend, that it contains the odd harmonic 2n-1 'overtone-series'
at the note-names for the generalized tonic 8-fold chord:

@:v:Q:j:I:X:p:e == 1:3:5:7:9:11:13:15 == D.:A.:Gb:C\:E.:G+:A&:Db

that fits also for the corresponding dominat- and subdominat chord.

Quest:
Sounds that 'addition-of-flavor' against 53-edo 'sharp-enough'
likewise in yours ears too, when perceiving by listening to that?

I'm interested in what actual music using this system would sound like. I'm having trouble imagining it.

...consists in mastering of performing that series
with your own lips on an brass-instrument, especially on an:

"...by playing in the extreme upper register and "lipping" the notes of the 11th and 13th harmonics (that is, flattening or sharpening those impure harmonics into tune with the embouchure), it was possible to play diatonic major and minor scales (and, hence, actual melodies) on a natural trumpet. The most talented players were even able to produce certain chromatic notes outside the harmonic series by this process (such as lipping a natural C down to B), although these notes were mostly used as brief passing tones. (In Germany, this technique was called Heruntertreiben, literally "driving down".) Other "impure" harmonics (such as the 7th and 14th - Bâ on an instrument pitched in C - which are very flat) were avoided by most composers, but were sometimes deliberately used, for example, where their unusual sonic qualities would complement the accompanying text in a sacred work..."

There the postition and the nor of the 13th partial within the overtone-series is labeled in red color,

the detuned ordinary 12-edo concept.

For comprehending that natural enriched sonority,
try to internalize the sound-examples of that euphony
by studying the pertinent demonstrations in:

Or simply just listen how the voices do actually sound:

It seems like you completely misunderstood me. I'm quite familiar with the sound of the 13th harmonic in the context of the harmonic series. But the scale you posted was not the harmonic series; it was something quite different.

Where is actual music that uses *that scale*?

ok Keenan,
but i only wrote, that my 53 ratios do contain
the harmonic series up to 13-limit as subset

Sorry,
at the moment performances do exist
still only in life improvisations on my
horn and violon-cello.
