'''9/8 equal temperament''' or '''1ed9/8''' is the use of a just [[9/8]] whole tone as the basis of an equal temperament tuning. It results in an interesting non-octave tuning. As every interval is a multiple of 9/8, the resultant tuning would be a subset of [[3-limit|3-limit]] [[Just_intonation|Just Intonation]]. This can be also viewed as generating a subset of [[baldy]] temperament.

Merge into 9/8?

9/8 equal temperament or 1ed9/8 is the use of a just 9/8 whole tone as the basis of an equal temperament tuning. It results in an interesting non-octave tuning. As every interval is a multiple of 9/8, the resultant tuning would be a subset of 3-limit Just Intonation. This can be also viewed as generating a subset of baldy temperament.
