~~The~~ '''tutonic hexad''' is an [[essentially tempered chord]] of the [[tutone]] temperament, which is every other member of the [[generator]] chain of [[11-limit]] [[meantone]] ([[Huygens]]~~). This means it is 9/8-9/8-9/8-9/8-9/8-8/7~~ tempered by {[[81/80]], [[99/98]], [[126/125]]~~}, or in other words the tempering of 9/8-5/4-7/5-11/7-7/4-2~~.

A '''tutonic hexad''' is an [[essentially tempered chord]] of the [[tutone]] temperament, which is every other member of the [[generator]] chain of [[11-limit]] [[meantone]] (also called as [[Huygens]], tempered by [[81/80]], [[99/98]] and [[126/125]]).

There are eight hexads as [[11-odd-limit]] essentially tempered chords of the 11-limit meantone, all of them are available in the tutone temperament; in other words, all of the essentially tempered hexads of the 11-limit meantone are tutonic hexads.

The palindromic hexads are

* 1-9/8-5/4-7/5-14/9-7/4 with steps of 9/8-9/8-9/8-9/8-9/8-8/7 ([[Didymic chords|erato hexad]], tempered by 81/80 and 126/125);

* 1-9/8-9/7-10/7-11/7-7/4 with steps of 9/8-8/7-9/8-11/10-9/8-8/7 (euterpe hexad, tempered by 81/80 and 99/98);

* 1-9/8-9/7-7/5-8/5-7/4 with steps of 9/8-8/7-11/10-8/7-11/10-8/7 (minerva hexad, tempered by 99/98 and 176/175);

* 1-9/8-5/4-7/5-8/5-7/4 with steps of 9/8-9/8-9/8-8/7-11/10-8/7 (minerva hexad, tempered by 99/98 and 176/175).

The inversely related pairs of hexads are

* 1-9/8-5/4-10/7-11/7-7/4 with steps of 9/8-9/8-8/7-11/10-9/8-8/7, and its inverse

* 1-9/8-11/9-7/5-11/7-7/4 with steps of 9/8-11/10-8/7-9/8-9/8-8/7;

* 1-9/8-9/7-7/5-11/7-7/4 with steps of 9/8-8/7-11/10-9/8-9/8-8/7, and its inverse

* 1-9/8-5/4-11/8-11/7-7/4 with steps of 9/8-9/8-11/10-8/7-9/8-8/7.
