Forms
unisson m (uncountable)[1] First written unison (1372); the spelling unisson is a 16th-century remaking.[2]
Etymology
It is borrowed from Medieval Latin ūnisonus (“of a single sound”),[2][3][4] an adjective meaning “of uniform sound, monotonous” found in Boethius in the 6th century,[5] compounded of ūnus (“one”) and sonus (“sound”).[5][2][6] The TLFi calls the source scholastic Latin,[5] the GLLF Late Latin.[7]
Earliest recorded meaning
It is first found in Nicole Oresme's translation of Aristotle's Politics (1372–1374), for the harmony of voices or instruments sounding the same note at the same time.[5][2]
Semantic evolution
As a term of music it names a single sound produced by several voices or instruments;[2] the phrase à l'unisson “sounding the same notes together” is recorded by the Académie in 1694.[5][2] By analogy Du Bellay (1549) used it as an adjective of words that rhyme to the ear but not to the eye.[2]
Montaigne (1588) used it figuratively for a sameness of thought, writing that l'unisson est qualité du tout ennuyeuse en la conference “agreement is a wholly tedious quality in conversation”.[5][6] From there come à l'unisson de “in harmony with” (1730, Du Marsais) and the adverbial à l'unisson “in accord” (1735, Gresset),[5][2] by the same figure as au diapason.[2]
