harmóníu

Harmóníu is the concept of accord or balance among parts within a system. The term derives from the Greek harmonia, meaning "joint or agreement," via Latin harmonīa and into various languages as harmóníu or close cognates. In everyday usage, harmóníu can refer to musical balance, social cohesion, or the orderly relation of elements in a design or theory.

In music, harmóníu denotes the horizontal and vertical aspects of pitch organization. It encompasses chords, chord progressions, and the sense of key or mode that underpins melodies. In Western tonal practice, functional harmony links chords through roles such as tonic, subdominant, and dominant, guiding tension and resolution. Other musical traditions may emphasize drones, polyphony, or modal relationships without the same functional chord system.

In philosophy and aesthetics, harmóníu is the principle of coherence, proportion, and unity among the parts of a whole. It is used to describe works that balance variety and order, and to express a state of ethical or social concord. In social contexts, harmóníu suggests peaceful coexistence among diverse groups, often achieved through shared norms, institutions, and communicative practices.

Because it covers multiple domains, the term is used in music theory, cultural studies, design, and political discourse, and its precise meaning depends on context.
