696edo is a strong 7-limit tuning, but unfortunately it is consistent only up to the [[9-odd-limit]]. In the | 696edo is a strong 7-limit tuning, but unfortunately it is consistent only up to the [[9-odd-limit]]. In the 5-limit, it tempers out the schisma, and in the 7-limit, the landscape comma. It supports the [[magnesium]] temperament which divides the octave in 12, as well as [[chromium]] temperament that divides it in 24. | ||
Nonetheless despite inconsistency, it is a valuable xenharmonic system. It provides the [[optimal patent val]] for the [[octant]] temperament in the 13-limit, even if its approximation of 13 is almost half a step off. Likewise, 696edo tunes [[altierran]] and [[house]] temperaments in the 11-limit. | Nonetheless despite inconsistency, it is a valuable xenharmonic system in higher limits. It provides the [[optimal patent val]] for the [[octant]] temperament in the 13-limit, even if its approximation of 13 is almost half a step off. Likewise, 696edo tunes [[altierran]] and [[house]] temperaments in the 11-limit. In the higher limits, it may be used as a 2.3.5.7.17.31 subgroup tuning. | ||
The 696cc val is also very close to the [[POTE]] tuning for the [[witcher]] temperament, while 696f tunes [[semiterm]] and the inaccurate 696d tunes [[pontic]]. | The 696cc val is also very close to the [[POTE]] tuning for the [[witcher]] temperament, while 696f tunes [[semiterm]] and the inaccurate 696d tunes [[pontic]]. | ||

Since 696 factors as {{Factorization|696}}, 696edo has subset edos {{EDOs|1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348}}. | |||
