Dyad (music)

All dyads within an octave on C. Template:Audio

In music, a dyad (less commonly, diad) is a set of two notes or pitches.<ref>Template:Cite encyclopedia</ref> The notes of a dyad can be played simultaneously or in succession. Notes played in succession form a melodic interval; notes played simultaneously form a harmonic interval.

Dyads can be classified by the interval between the notes.<ref>Template:Cite web</ref> For example, the interval between C and E (four half steps) is a major third, which can imply a C major chord, made up of the notes C, E and G.<ref>Young, Doug (2008). Mel Bay Presents Understanding DADGAD, p.53. Template:ISBN.</ref>

In a triadic context chords with omitted thirds may be considered "indeterminate" triads.<ref name="Benjamin">Benjamin, et al. (2008). Techniques and Materials of Music, p.191. Template:ISBN.</ref> Template:Audio
