+'''Enneacot''' is a temperament archetype where the generator is a small semitone, nine of which make a perfect fifth of [[3/2]], and the period is a [[2/1]] octave. Enneacot temperaments also include all [[Ploidacot/Tricot|tricot]] intervals, as the tricot generator is split further into three.
-Enneacot temperaments generate the [[15L 1s]] MOS scale, and are mostly famous in the form of the [[Carlos Alpha]] scale, which is usually perceived as multiple independent chains of enneacot generators offset by octaves.

 == Intervals and notation ==
 Due to dividing the fifth into so many steps, standard notation becomes almost useless for enneacot. Regardless, notation has been provided for where [[Ploidacot/Monocot|monocot]] intervals appear in this system.

 == Temperament interpretations ==
 === Valentine ===
-Valentine is the standard [[regular temperament]] interpretation of the Carlos Alpha scale as an ET. 5 generators is 5/4, 4 is 6/5, and 3 is 8/7. It can be extended to the 11-limit by setting 7 steps to 11/8, and to the 13-limit by setting 11 steps to 13/8.

It can be extended to the 11-limit by setting 7 steps to [[11/8]]; [[Valentine extensions|a few mappings]] of 13 are possible, the most accurate of which maps 20 generators to [[32/13]].
