Forms

harmonicus (feminine harmonica, neuter harmonicum); first/second-declension adjective[1]

Etymology

It is borrowed from Ancient Greek ἁρμονικός (harmonikós),[1][2][3] from ἁρμονία (harmonía, “joining, fitting”).[3]

Earliest recorded meaning

Varro (116–27 BC) is the first to use it, in De lingua Latina, of proportions that craftsmen observe in buildings and statues.[4][3]

Semantic evolution

In Classical Latin it is rare and means “according to natural proportion”: Pliny the Elder speaks of a harmonica ratio that makes nature agree with itself, and Martianus Capella of harmonious ringing.[2][1][5] Medieval writers used it in philosophy for things well ordered by proportion, and in music for consonant, musical sounds and for music theory,[6] and Niermeyer records it as a noun for a musician.[7] English took harmonic from it in the 1560s, first meaning “relating to music”.[8]
