# Valinorsmic chords

A **valinorsmic chord** is a valinorsma (176/175) tempered essentially tempered chord in the 2.5.7.11 subgroup in the 11-odd-limit. There are three valinorsmic triads: the valinorsmic version of the augmented triad,

- 1-5/4-8/5 with steps 5/4-14/11-5/4,

and an inversely related pair,

- 1-8/5-7/4 with steps 8/5-11/10-8/7 and 1-8/7-5/4 with steps 8/7-11/10-8/5.

Valinorsmic tetrads are six in number, consisting of two palindromic chords and a pair of pairs of inversely related chords. The palindromes are

- 1-11/10-5/4-7/4 with steps 11/10-8/7-7/5-8/7 and
- 1-11/10-5/4-11/8 with steps 11/10-8/7-11/10-16/11.

The rest are

- 1-5/4-8/5-7/4 with steps 5/4-14/11-11/10-8/7 and 1-5/4-10/7-11/7 with steps 5/4-8/7-11/10-14/11, plus
- 1-5/4-11/8-11/7 with steps 5/4-11/10-8/7-14/11 and 1-11/10-11/8-7/4 with steps 11/10-5/4-14/11-8/7.

Finally, there are the two inversely related pentads,

- 1-11/10-5/4-8/5-7/4 with steps 11/10-8/7-14/11-11/10-8/7 and 1-11/10-5/4-11/8-7/4 with steps 11/10-8/7-11/10-14/11-8/7.

The count is triads: 3, tetrads: 6, pentads: 2; 11 in total.

If we are willing to go to the 15-odd-limit, we get four alternative, valinorsmic, temperings of the four keenanismic tetrads which have steps which are permutations of the otonal/utonal 7-limit tetrads. The reason for the similarity between valinorsmic and keenanismic tetrads is that they both temper 48/35, valinorsmic to 15/11 and keenanismic to 11/8. Another valinorsmic tetrad has steps 11/9-6/5-8/7-6/5, leading to 1-11/9-22/15-5/3 chords.

Equal temperaments with valinorsmic chords include 22, 31, 43, 46, 53, 58, 68, 80, 89, 111 with 111edo giving the optimal patent val.
