A '''nonoctave''' scale is a scale whose equivalence interval is not the [[octave]] (2/1).

Nonoctave scales come in many varieties, but what unites them is an aversion of [[octave]]s. A common approach to building a sensible scale without octaves is to divide some nonoctave interval into logarithmically [[Equal|equal]] parts, as one would divide the octave to arrive at an [[EDO|EDO]]. Such a scale is sometimes called an [[edonoi|EDONOI]], short for "equal divisions of a nonoctave interval". One can also build rational scales with nonoctave repeats or no repeat (e.g. [[Superparticular-Nonoctave-MOS|Superparticular-Nonoctave-MOS]]). Nonoctave scales may contain a "near octave" or "tempered octave" which would be an interval near but not exactly 1200¢. In this category, there are stretched octaves and compressed octaves, each having their own character.

Here are only a few reasons. Add your own!

Composers and theorists known for their work in nonoctave scales include [[X._J._Scott|X. J. Scott]]; [[Wendy_Carlos|Wendy Carlos]]; [[Gary_Morrison|Gary Morrison]]; [[Carlo_Serafini|Carlo Serafini]]; and [[Heinz_Bohlen|Heinz Bohlen]], [[John_Pierce|John Pierce]], and [[Kees_van_Prooijen|Kees van Prooijen]], the latter trio being associated with the [[Bohlen-Pierce|Bohlen-Pierce]] scale.
