# User talk:Contribution

## When I suggested to switch to JavaScript

on Talk:31-limit, I did not primarily think on doing it right within the Wiki. I even think that user-specific JS isn't enabled here ...

Is there any place where this could be tried out first without fighting against wiki limitations of some sort?

Hello, I have a Wordpress website under construction but I don't know JavaScript. Best regards.

- I see, I am also a newcomer in this respect, but it seems to be the current
**hottest language**. If I get an idea what your point is, I could try to implemenent it somewhere. As I understand it so far, there is a big 1 in the middle and then a Cartesian coordinate system around it with prime factors not exceeding 31 above or below the fraction line, right? --Xenwolf (talk) 18:45, 14 May 2020 (UTC)

Yes, the rules are :

1) 1/1 is the center of symmetry between reciprocals.

2) The positive abscissa is the Pythagorean scale. The negative abscissa is deducted by rule 1.

3) The positive ordinate is the 5-31 quasi-primes scale, presented as follow:

a ; a*a ;

b ; a*b ; a^{-1}*b ; b*b ;

c ; a*c ; a^{-1}*c ; b*c ; b^{-1}*c ; c*c ;

d ; a*d ; a^{-1}*d ; b*d ; b^{-1}*d ; c*d ; c^{-1}*d ; d*d ; etc...

The negative ordinate is deducted by rule 1.

4) 5-limit allows also a*a*a and its symmetrical reciprocal

Below is a piece of Python code doing it (better solutions may be possible):

primes=[2,3,5,7,11,13,17,19,23,29,31] # reciprocal of a given monzo def reciprocal(monzo): for p in range(0,len(monzo)): monzo[p]*=-1 return(monzo) # ABSCISSA MONZOS LIST x_axis=[] for a in range(0,26+1): # pythagorean interval monzo=[0]*len(primes) monzo[1]+=a # insert it at the end of the list x_axis.append(monzo) # insert its reciprocal at the beginning of the list, so that 1/1 is the center of symmetry between reciprocals x_axis.insert(0,reciprocal(monzo.copy())) # ORDINATE MONZOS LIST y_axis=[] # insert 1/1 monzo=[0]*len(primes) y_axis.insert(0,monzo) # first prime for a in range(2,len(primes)): # pure harmonic series monzo=[0]*len(primes) monzo[a]+=1 # insert the pure harmonic at the beginning of the list y_axis.insert(0,monzo) # insert its subharmonic version at the end of the list, so that 1/1 is the center of symmetry between reciprocals y_axis.append(reciprocal(monzo.copy())) # second prime for b in range(2,a+1): # combine the pure harmonic with another prime, both by putting it in the numerator or in the denominator for c in range(1,-1-1,-2): monzo=[0]*len(primes) monzo[a]+=1 # when c=1, the second prime is put in the numerator ; when c=-1, the second prime is put in the denominator monzo[b]+=c # before inserting, eliminate the cases where the first and the second prime are reciprocal if(monzo!=[0]*len(primes)): # insert the combination at the beginning y_axis.insert(0,monzo) # insert its reciprocal at the end, so that 1/1 is the center of symmetry between reciprocals y_axis.append(reciprocal(monzo.copy())) # insert 125/64 exception and its reciprocal if(monzo==[0,0,2,0,0,0,0,0,0,0,0]): monzo[2]+=1 y_axis.insert(0,monzo) y_axis.append(reciprocal(monzo.copy())) # CARTESIAN COORDINATE PLANE OF MONZOS table=[] for y in range(0,len(y_axis)): row=[] for x in range(0,len(x_axis)): monzo=[] for a in range(0,len(primes)): # combine the abscissa monzo and the ordinate monzo monzo.append(x_axis[x][a]+y_axis[y][a]) row.append(monzo) table.append(row) ##### SHOW RESULT ##### print(table)

Would be curious to see your implementation :)

## Subpage helper

Hi Contribution,

You might be interested in a wiki function that creates an inline list of subpages: `{{Special:PrefixIndex/{{FULLPAGENAME}}/}}`

(could be helpful on your user page).

Best regards

## Factor limit suggestion

Hi Contribution,

Your **factor limit** idea looks quite interesting to me. Just a few thoughts:
*1-factor-limit* seems to include the prime harmonic series and its inverse (and what about *0-factor-limit* being *1*)?.

Maybe also the (obviously abandoned) prime interval attempt could be worth reading (some open questions there).

## Moving pages around

Hi Contribution,

I've seen you move wiki pages to strange places after you deleted their content. Maybe it's your way to try to get a page "deleted" somehow.

I built a tool to say "please delete this page" to one of the operators. A short description is on Help:Help, I hope that helps.

Best regards --Xenwolf (talk) 18:30, 20 June 2020 (UTC)

## A BIG Thanks

... for all the work you did adding all the Helmholtz-Ellis notation symbols! Especially that you did it in SVG, make them an ideal base for derivates and images using them. Thanks again. --Xenwolf (talk) 08:31, 4 October 2020 (UTC)

## Reduce comma tables on EDO pages

Please have a look at Xenharmonic Wiki: Things to do #Comma tables in EDO_pages. Thanks --Xenwolf (talk) 09:10, 11 January 2021 (UTC)

## Huge Tables

I think that the tables you are adding are a usability nightmare. Do you really think they are good for the wiki? --Xenwolf (talk) 17:48, 13 April 2021 (UTC)

- I agree with Xenwolf honestly, especially in light of some of the things currently being discussed on the Xenharmonic Alliance Discord Server. --Aura (talk) 20:48, 13 April 2021 (UTC)

## equal contrary motion

Hi contribution,

I think it would ease to understand this voice leading concept it there was some article of at least section (reachable via redirect). Do you think you could explain (and illustrate) it a bit further?

Thanks in advance. --Xenwolf (talk) 21:00, 3 October 2022 (UTC)

- According to Wikipedia: Contrapuntal motion, another name for equal contrary motion is "strict contrary motion". I don't think it is necessary to redefine basic voice leading concepts here on the Xen Wiki, since it is possible to link to Wikipedia whenever such a definition might be judged necessary. I think adding pictures would help more than adding definitions.

- That said, I would see no problem if there were pages about examples of voice leading specific to some tunings, when there is too much content to keep it reasonably on the tuning's main page. --Fredg999 (talk) 02:28, 4 October 2022 (UTC)

Hello,

What kind of intervals does the concept of strict contrary motion refer to? Degrees of a scale (for example 1 degree of 12 tones), or size (for example 100 cents)? Could all contrary motion of the same amount of degrees in an irregular temperament still be called strict?

## Template: Infobox ZPI

The template you created calls an inexistent module. If this template is work in progress, please add `[[Category:Draft templates]]`

and don't use it in other pages until its basic functionality is complete. Thank you in advance. FloraC (talk) 13:19, 28 March 2024 (UTC)
