Forms

ἁρμονῐκός (harmonikós) m (feminine ἁρμονῐκή, neuter ἁρμονῐκόν); first/second declension[1]

Etymology

It is from Ancient Greek ἁρμονία (harmoníā, “fitting together; harmony”) + -ικός (-ikós).[1][2]

Earliest recorded meaning

Plato's Phaedrus has it of a man skilled in music: μουσικὸς ἐντυχὼν ἀνδρὶ οἰομένῳ ἁρμονικῷ εἶναι, “a musician who meets a man who believes himself an expert in harmony”.[3][4][5]

Semantic evolution

In Plato and Aristotle the neuter plural means the theory of music, and the feminine, with “science” understood, the mathematical theory of music, one of the mathematical sciences.[3][6][4] The masculine plural names the theorists of music, and Aristotle speaks of those who work by numbers, and Theophrastus also uses it.[3][6] Aristoxenus called his treatise Elements of Harmonics.[3][4] Archytas named the third of the three means of music, beside the arithmetic and the geometric, the harmonic mean, and later arithmetic kept the term for a mean and a proportion.[4][3]

Plutarch uses it of the enharmonic scale, and figuratively of a person able to bring things into harmony; he also reports that the god is called harmonic and musical.[3][4] Galen speaks of a harmonic movement of the pulse, in keeping with the state of the body, and Philostratus of training by rule of thumb.[3]

It was borrowed into Latin harmonicus, from which English harmonic, first “relating to music” in the 1560s, and French harmonique come.[7][1] The modern Modern Greek αρμονικός (armonikós) is learned, partly a semantic loan from the French word; it means harmonious, well proportioned, and musical.[8]
