'''Ennealimmal''' is a [[regular temperament|temperament]] with a period of {{frac|1|9}} octave and tempers out [[2401/2400]] and [[4375/4374]]. Edos that support ennealimmal include {{EDOs| 27, 45, 72, 99, 171, 270, 441, and 612 }}. | |||

Ennealimmal scales are built from a ''period'' (which is exactly {{frac|1|9}} of an octave), and a ''generator'' (which is approximately 49 cents and represents several small intervals including 36/35). Depending on the size of the generator and the period in steps, the above listed edos make sense: | |||

7-limit 81-odd-limit: 0.408 ¢
7-limit 81-odd-limit: 99 notes
Ennealimmal is a temperament with a period of 1⁄9 octave and tempers out 2401/2400 and 4375/4374. Edos that support ennealimmal include 27, 45, 72, 99, 171, 270, 441, and 612.
See Septiennealimmal clan #Ennealimmal for technical data.
Ennealimmal scales are built from a period (which is exactly 1⁄9 of an octave), and a generator (which is approximately 49 cents and represents several small intervals including 36/35). Depending on the size of the generator and the period in steps, the above listed edos make sense:
| Period (steps) | Generator (steps) | Generator (cents) (pure octave) |
Edo |
|---|---|---|---|
| 3 | 1 | 44.444 | 27 |
| 11 | 4 | 48.485 | 99 |
| 30 | 11 | 48.889 | 270 |
| 19 | 7 | 49.123 | 171 |
| 8 | 3 | 50.000 | 72 |
| 5 | 2 | 53.333 | 45 |
Ennealimmal extends less well to the 11-limit. Extensions include enneabiotic (99e & 270), ennealympic (171 & 270), ennealimnic (72 & 99e), and ennealiminal (72 & 171e).
See Ennealimmal extensions for a discussion on 11-limit extensions.
