| “Equiheptatonic” scales are scales with 7 roughly equally spaced tones per [[octave]]. They are usually not exactly equally spaced, but deviate from equal by small amounts, often to improve the tuning of [[3/1]] and [[5/1]].
| | [[Equiheptatonic]] scales are scales with 7 ''roughly equally'' spaced tones per [[octave]], common in some musical traditions. The exactly equal form of the equiheptatonic scale is [[7edo]]. |
| | |
| Musical traditions that make use of equiheptatonic scales include:
| |
| * Eastern [[Angolan]] music
| |
| * [[Cambodian]] classical music
| |
| * [[Ancient Greek]] auloi music
| |
| * [[Laotian]] classical music
| |
| * [[Thai]] classical music
| |
| * [[Vietnamese]] classical music
| |
| * Lower [[Zambezi]] music
| |
| ** [[Nyungwe]] music
| |
| Note that just because a tradition has an equiheptatonic scale doesn’t mean it uses it exclusively. They often have other tunings too. Also, the term “scale” here is used loosely, because many, perhaps the majority, of musical traditions don’t use scales, but use something else like tetrachords, raag, etc. that scales can only loosely model.

| | |
| An exactly equal equiheptatonic scale is [[7edo]], which is popular with modern Western xenharmonic composers.
