Original Wikitext content:
The //structure metric// is a [[https://en.wikipedia.org/wiki/Metric_(mathematics)|distance function]] on the period-equivalenced notes of a [[constant structure]] [[periodic scale]] which give to it the property of being a [[https://en.wikipedia.org/wiki/Metric_space|finite metric space]]. If **s** is a periodic scale with quasiperiod **P**, and if **s**[i] is a note of **s**, then we may define the base points set base(**s**[i]) to be the set of integers {j|**s**[j+i] - **s**[j] = **s**[i]}. Reducing these modulo **P** to the range 0 ... **P**-1 gives a finite set of period-equivalenced notes.Original HTML content:
