Some temperaments have 11/9 as a "neutral third", meaning it's exactly half of a 3/2 (tempering out 243/242), and other temperaments (in the [[gamelismic clan]]) have 8/7 as exactly a third of 3/2. Miracle is distinguished by doing both of these things at the same time, so 3/2 is divided into six equal parts. This is in fact the generator of miracle temperament, called a "secor", and it represents both 16/15 and 15/14.

Original Wikitext content:

Miracle is an exceptionally efficient linear temperament which is a member of both the [[marvel temperaments]] and the [[gamelismic clan]]. It is quite accurate, with TOP error only 0.63 cents/octave, meaning intervals of the 11-limit tonality diamond are represented with only one or two cents of error. Yet it is also very "low complexity" (efficient), as evidenced by the high density of 11-odd-limit ratios (in bold) in the following table:
|| number of secors || 0 || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 ||
|| JI intervals represented || **1/1** || 16/15~15/14 || **8/7** || **11/9** || 21/16 || **7/5** || **3/2** || **8/5** || **12/7** || **11/6** ||
|| number of secors || 10 || 11 || 12 || 13 || 14 || 15 || 16 || 17 || 18 || 19 ||
|| JI intervals represented || 63/32~55/28~108/55~49/25~96/49~88/45 || 22/21~21/20 || **9/8** || **6/5** || **9/7** || **11/8** || 22/15 || **11/7** || 42/25 || **9/5** ||

|| JI intervals represented || 48/25~27/14 ||   || **11/10** ||   ||   ||   ||   ||   ||   ||   ||
Some temperaments have 11/9 as a "neutral third", meaning it's exactly half of a 3/2 (tempering out 243/242), and other temperaments (in the [[gamelismic clan]]) have 8/7 as exactly a third of 3/2. Miracle is distinguished by doing both of these things at the same time, so 3/2 is divided into six equal parts. This is in fact the generator of miracle temperament, called a "secor", and it represents both 16/15 and 15/14.

Miracle can also be thought of as a [[cluster temperament]] with 10 clusters of notes in an octave. The small chroma interval between adjacent notes in each cluster is very versatile, representing 45/44~49/48~50/49~55/54~56/55~64/63 all tempered together.
