<h2>IMPORTED REVISION FROM WIKISPACES</h2>
A '''prodigy chord''' is an [[11-odd-limit]] [[essentially tempered chord]] in [[prodigy]] temperament. Since [[441/440]] is tempered out in prodigy, [[werckismic chords]] are also prodigy chords, and since [[225/224]] is tempered out, the [[9-odd-limit]] [[marvel chords]] are prodigy chords. Aside from these, there are three more prodigy chords, with a palindromic tetrad:

[[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.
{{Main| Miracle chords }}


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. In miracle, we may put the eight different kinds of essentially tempered chords together, for a total of triads: 21, tetrads: 74, pentads: 32, and hexads: 10. There are therefore actually more essentially tempered chords than just ones.
