Aside from these, there are three more prodigy chords: a 1-5/4-7/5-16/9 tetrad with steps 5/4-9/8-14/11-9/8 and a pair of inversely related pentads, 1-5/4-7/5-8/5-16/9 with steps 5/4-9/8-8/7-10/9-9/8 and 1-5/4-7/5-14/9-16/9 with steps 5/4-9/8-10/9-8/7-9/8. | ||
Equal divisions with prodigy chords include 12, 29, 31, 41, 43, 72, 74, 84, 103, 175, 197, 247c, 3129bcde, 391bcde and 463bcde.</pre></div> | Equal divisions with prodigy chords include 12, 29, 31, 41, 43, 72, 74, 84, 103, 175, 197, 247c, 3129bcde, 391bcde and 463bcde. | ||

[[Gamelismic clan#Miracle|11-limit miracle temperament]] tempers out an astonishing five commas which allow essential tempering: 540/539, 441/440, 385/384, 243/242 and 225/224, and hence has all of the essentially tempered chords of each of them. Further chords come from [[Breed family#Jove, aka Wonder|jove]] and 9- and 11-marvel chords. Finally, there are the three listed above. | |||
Three chords may not seem by many, but consider this: the POTE tuning for prodigy shrinks 540/539 and 243/242 to a third of a cent, and 385/384 to -1/3 cent. Other optimizations are similar. Hence, the miracle essentially tempered chords are already available in prodigy, we just aren't counting them; in effect, we can more or less equate prodigy with miracle.</pre></div> | |||
