“Equihexatonic” scales are scales with 6 roughly equally spaced tones per [[octave]]. Equihexatonic scales are rare in the world’s musical traditions, with one big exception: the whole tone scale of modern Western music. It is an equihexatonic scale, so equi-, in fact, that it is exactly [[6edo]]. | “Equihexatonic” scales are scales with 6 roughly equally spaced tones per [[octave]].

A hexatonic system of interval classification may be desired in the [[2.5.7 subgroup]], since 6edo represents it well for its size. Several extensions of the 2.5.7 subgroup, such as 2.9.5.7, 2.5.7.11, and 2.9.5.7.11, are also represented relatively accurately in 6edo. | |||
Although equihexatonic scales may be rare, unequal hexatonic scales occur fairly commonly in the world’s musical traditions, especially in the folk music of some parts of Europe. | Although equihexatonic scales may be rare, unequal hexatonic scales occur fairly commonly in the world’s musical traditions, especially in the folk music of some parts of Europe. | ||

Curiously, the Scottish hexatonic, hexatonic minor, minor blues and major blues scales are all constructed by adding one note to a [[2L 3s]] MOS scale. It is curious that they share this common structure - but also useful, as it suggests that maybe, even outside of 12edo, adding a note to 2L 3s could be a productive way of developing useful hexatonic scales in any tuning which supports that MOS (including most [[EDO]]s). | Curiously, the Scottish hexatonic, hexatonic minor, minor blues and major blues scales are all constructed by adding one note to a [[2L 3s]] MOS scale.
