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 equivalent and are elements of the same pitch class. The term equave was coined by Inthar.
Examples
- In octave-equivalent scales, the equave is 2/1.
- In Bohlen-Pierce, the equave is 3/1.
- In edfs, the equave is 3/2.
