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.
