In a [[periodic scale]], the '''equave''' (/ˈiːkwɪv/ ''EE-kwiv'' or /ˈiːkwəv/ ''EE-kwəv''), also called '''interval of equivalence''' or '''equivalence interval''', is the interval such that pitches separated by it are considered [[equivalence|equivalent]] and are elements of the same [[pitch class]]. The term ''equave'' was coined by [[User:Inthar|Inthar]].

In a [[periodic scale]], the '''equave''' (/ˈiːkwɪv/ ''EE-kwiv'' or /ˈiːkwəv/ ''EE-kwəv''), also called '''interval of equivalence''', '''equivalence interval''', '''formal octave'''<ref>Op de Coul, E.F. [https://www.huygens-fokker.org/scala/help.htm Scala help.]</ref> or '''pseudo-octave'''<ref>[https://help.ableton.com/hc/en-us/articles/10998372840220-ASCL-Specification ASCL Specification]. Ableton.</ref>, is the interval such that pitches separated by it are considered [[equivalent]] and are elements of the same [[pitch class]].  
 
The equave of a scale is generally the same as its [[period]] or a multiple of its [[period]].
 
== Etymology ==
The term ''equave'' was coined by [[User:Inthar|Inthar]]. It is a portmanteau of ''equivalence'' and ''octave''.
