A '''werckismic chord''' is an [[essentially tempered dyadic chord]] in [[Werckismic temperaments|werckismic]] ([[441/440]]) tempering in the 2.9.5.7.11 [[Just intonation subgroup|subgroup]] in the [[11-odd-limit]].
A '''werckismic chord''' is an [[essentially tempered dyadic chord]] tempered by the werckisma, [[441/440]].  


The werckismic [[Triad|triads]] consist of three pairs of inversely related chords:
Werckismic chords are of [[Dyadic chord/Pattern of essentially tempered chords|pattern 2]] in the [[11-odd-limit]], meaning that there are 6 [[triad]]s, 15 [[tetrad]]s and 6 [[pentad]]s, for a total of 27 distinct chord structures.  
* 1-11/9-7/5 with [[Step|steps]] 11/9-8/7-10/7 and 1-11/9-7/4 with steps 11/9-10/7-8/7;

The werckismic [[Tetrad|tetrads]] consist of three palindromic (self-inversive) chords and five pairs of chords in an inverse relationship. The palindromic chords are  
The werckismic triads consist of three pairs of inversely related chords:

The werckismic [[Pentad|pentads]] consist of three pairs of chords in an inverse relationship:
[[Equal temperament]]s with werckismic chords include {{EDOs| 31, 41, 43, 46, 58, 72, 77, 84, 103, 118, 130, 159, 171, 190, 248, 289, and 320 }}, with [[320edo]] giving the [[optimal patent val]].
