This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The septiennealimmal clan of temperaments tempers out the septimal ennealimma (monzo: [-11 -9 0 9⟩, ratio: 40353607/40310784). Primarily, this clan includes the 7-limit ennealimmal temperament and extensions of it.

Temperaments discussed elsewhere are:

No-five septiennealimmal

This rank-2 temperament is of interest to anyone who wants a different generator for the ennealimmal-like structure because it represents the part of ennealimmal supported by non-ennealimmal equal temperaments of interest that do well in the 2.3.7 subgroup, such as 36edo, which adds the gamelisma, or 63edo, which in the 7-limit can be used for magic and in higher limits for parapyth among other things.

Septiennealic

Septiennealic finds a somewhat high-damage but very simple and intuitive mapping of prime 13 by fixing 13/12~14/13 at 1\9.

A notable tuning of septiennealic not appearing in the optimal ET sequence is 63edo. If we include a somewhat more complex mapping for 11 via 36e & 63, it will become the optimal patent val and largest in the sequence.

Ennealimmal

Main article: Ennealimmal
For the 5-limit version, see Ennealimma #Ennealimmal.

Ennealimmal tempers out the two smallest 7-limit superparticular commas, 2401/2400 and 4375/4374, leading to a temperament of unusual efficiency. It also tempers out the landscape comma, which is (2401/2400)/(4375/4374), and the wizma, which is (2401/2400)⋅(4375/4374).

In the 5-limit, it tempers out the ennealimma, [1 -27 18⟩, which leads to the identification of (27/25)9 with the octave, and gives ennealimmal a period of 1/9 octave. Its pergen is (P8/9, P5/2), and ploidacot enneaploid dicot. While 27/25 is a 5-limit interval, a stack of two periods equates to 7/6 because of identification by 4375/4374, and this represents 7/6 with such accuracy (a fifth of a cent flat) that there is no realistic possibility of treating ennealimmal as anything other than 7-limit.

Aside from 10/9 which has already been mentioned, possible generators include 36/35, 21/20, 6/5, 7/5 and the neutral thirds pair 49/40~60/49, all of which have their own interesting advantages. Possible tunings are 441-, 612-, or 3600edo, though its hardly likely anyone could tell the difference.

If 1/9 of an octave is too small of a period for you, you could try generator-period pairs of [3, 5], [5/3, 3], [6/5, 4/3], [4/3, 8/5] or [10/9, 4/3] (for example). In particular, people fond of the idea of "tritaves" as analogous to octaves might consider the 28- or 43-note mos with generator an approximate 5/3 within 3; for instance as given by 451/970 of a "tritave". Tetrads have a low enough complexity that (for example) there are nine 1–3/2–7/4–5/2 tetrads in the 28 notes to the tritave mos, which is equivalent in average step size to a 172⁄3 to the octave mos.

Ennealimmal extensions discussed elsewhere include omicronbeta.

7-limit ennealimmal's S-expression-based comma list is {S25/S27, S49}.

Hemiennealimmal

Hemiennealimmal (72 & 198) has a period of 1/18 octave and tempers out the four smallest superparticular commas of the 11-limit JI, 2401/2400, 3025/3024, 4375/4374, and 9801/9800. Tempering out 9801/9800 leads to an octave split into two equal parts. Notably, every one of these commas is part of one or more known infinite comma families; see directly below.

Its S-expression-based comma list is {(S22/S24 = S55 = S25/S27 × S99,) S25/S27, S49, S33/S35 = S99}.

Semiennealimmal

Semiennealimmal tempers out 4000/3993, and uses a ~140/121 semifourth generator. Notably, however, two generator steps do not reach ~4/3, despite that the name may suggest so. In fact, it splits the generator of ennealimmal into three.
