A '''dyad''' (less commonly, '''diad''') is a [[chord]] of two [[pitch class]]es. In its simplest voicing, a dyad contains two notes, but it may also contain [[octave]] doublings (assuming [[octave equivalence]]). For example, a [[Wikipedia:Power chord|power chord]] is a dyad because it contains only two pitch classes a [[perfect fifth]] apart, even though it usually contains at least three notes. | A '''dyad''' (less commonly, '''diad''') is a [[chord]] of two [[pitch class]]es.

Dyads can be classified by the [[interval]] between the notes, and as such the words ''dyad'' and ''interval'' are sometimes used interchangeably. | Dyads can be classified by the [[interval]] between the notes, and as such the words ''dyad'' and ''interval'' are sometimes used interchangeably, especially to distinguish from the mathematical sense of ''interval'' (connected subset of the real line). | ||
