In music, a dyad (less commonly, doad) is a set of two notes or pitches that, in particular contexts, may imply a chord. To understand dyads it is necessary first to understand the intervals between the notes. Take the notes C and E for example, we know that the interval between these two pitches is a major third, which can imply a C major chord (C E G). The most common two-note "chord" is the interval of a perfect fifth, which has been used in nearly all discovered pieces of polyphonic music. The reason fifths are so common is because of the harmonic series. The harmonic series is built over a fundamental pitch, and the rest of the partials in the series are called overtones. The second partial is an octave above the fundamental and the third pitch is a fifth, so if C is the fundamental pitch the second note is C an octave higher and then the next pitch would be G. The harmonic series has more fifths than just this one, for example the fourth to the sixth, the sixth to the ninth and the seventh to the eleventh partial are all a fifth away from each other, though the latter is of a slightly different size than the former ones. Since an interval is the distance between two pitches, a dyad can be classified by the interval it represents. When the pitches of a dyad occur in succession, they form a melodic interval. When they occur simultaneously, they form a harmonic interval.

Sociology defines dyad (from Greek dýo, "two" or Sanskrit "Dayadaha") as a group of two people, the smallest possible social group. As an adjective, "dyadic" describes their interaction.
The pair of individuals in a dyad can be linked via romantic interest, family relation, interests, work, partners in crime, and so on. The relation can be based on equality, but may be based on an asymmetrical or hierarchical relationship (master-servant).
The strength of the relationship is evaluated on the basis of time the individuals spend together, as well as on the emotional intensity of their relationship.
A dyad can be unstable because both persons must cooperate to make it work. If one of the two fails to complete their duties, the group would fall apart. Because of the significance of marriages in society, their stability is very important. For this reason marital dyads are often enforced through legal, economic, and religious laws.
Dyadic friendships refer to the most immediate and concrete level of peer interaction, which is expanded to include new forms of relationships in adolescence - most notably, romantic and sexual relationships. Already Ferdinand Tönnies treated it as a special pattern of gemeinschaft, 1887, as community of spirit.

Dyad is Michael Brodsky's fourth novel. It is narrated by an urban lowlife known only as X—. He is hired by the dying tycoon Jamms, who wants X— to convince Jamms's estranged artist son Jim to come home, and let bygones be bygones.
The "dyad" of the title refers to two people who are linked, what Beckett called a " pseudo-couple". X—, speaking about Jim, says:
As is clear from the above quotation, metafictional issues are present in the novel. X— makes frequent reference to the "story-mongers" and "meaning-mongers", and is constantly trying to figure out whether trivial matters that happen qualify as "incidents" or "events" or are otherwise "part of the story".
The Dyad is a title used by the Pythagoreans for the number two, representing the principle of "twoness" or "otherness".
Numenius of Apamea, a Neopythagorean philosopher in the latter 2nd century CE, said that Pythagoras gave the name of Monad to God, and the name of Dyad to matter. Aristotle equated matter as the formation of the elements (energies) into the material world as the static material was formed by the energies being acted upon by force or motion. Later Neoplatonic Philosophers and idealists like Plotinus treated the dyad as a second cause ( demiurge), which was the divine mind ( nous) that via a reflective nature (finiteness) causes matter to "appear" or become perceivable.
