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.

The werckismic triads consist of three pairs of inversely related chords:

* 1–7/5–11/7 with steps 7/5, 9/8, 14/11, and its inverse
* 1–14/11–10/7 with steps 14/11, 9/8, 7/5.
 
The werckismic tetrads consist of three palindromic (self-inversive) chords and five pairs of chords in an inverse relationship. The palindromic chords are
* 1–5/4–10/7–7/4 with steps 5/4, 8/7, 11/9, 8/7;
* 1–9/8–10/7–11/7 with steps 9/8, 14/11, 11/10, 14/11;
* 1–14/11–7/5–16/9 with steps 14/11, 11/10, 14/11, 9/8.
 
The pairs of chords are:
* 1–11/9–11/7–7/4 with steps 11/9, 9/7, 10/9, 8/7, and its inverse
* 1–9/7–11/7–9/5 with steps 9/7, 11/9, 8/7, 10/9;
* 1–10/7–11/7–7/4 with steps 10/7, 11/10, 10/9, 8/7, and its inverse
* 1–8/7–14/11–7/5 with steps 8/7, 10/9, 11/10, 10/7;
* 1–9/8–10/7–7/4 with steps 9/8, 14/11, 11/9, 8/7, and its inverse
* 1–11/9–14/9–7/4 with steps 11/9, 14/11, 9/8, 8/7;
* 1–11/9–11/8–7/4 with steps 11/9, 9/8, 14/11, 8/7, and its inverse
* 1–14/11–10/7–7/4 with steps 14/11, 9/8, 11/9, 8/7;
* 1–9/8–5/4–10/7 with steps 9/8, 10/9, 8/7, 7/5, and its inverse
* 1–10/9–5/4–7/4 with steps 10/9, 9/8, 7/5, 8/7;
* 1–9/8–9/7–10/7 with steps 9/8, 8/7, 10/9, 7/5, and its inverse
* 1–9/8–11/7–7/4 with steps 9/8, 7/5, 10/9, 8/7.
 
The werckismic pentads consist of three pairs of chords in an inverse relationship:
* 1–9/8–5/4–10/7–7/4 with steps 9/8, 10/9, 8/7, 11/9, 8/7, and its inverse
* 1–11/9–7/5–14/9–7/4 with steps 11/9, 8/7, 10/9, 9/8, 8/7;
* 1–11/9–11/8–11/7–7/4 with steps 11/9, 9/8, 8/7, 10/9, 8/7, and its inverse
* 1–9/8–11/8–11/7–7/4 with steps 9/8, 11/9, 8/7, 10/9, 8/7;  
* 1–9/8–9/7–10/7–11/7 with steps 9/8, 8/7, 10/9, 11/10, 14/11, and its inverse
* 1–9/8–10/7–11/7–7/4 with steps 9/8, 14/11, 11/10, 10/9, 8/7.
