Ennealimmal temperament has a period of 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.
See Ragismic microtemperaments #Ennealimmal for more 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 |
