Forms
unísono (feminine unísona, masculine plural unísonos, feminine plural unísonas)[1]
Etymology
It is borrowed from Late Latin ūnisonus (“having the same sound”), a learned word.[2][1][3] Corominas dates it to about 1440, in the Marqués de Santillana.[3][4] The Latin adjective is formed from ūnus (“one”) and sonus (“sound”).[1][5]
The same Latin word gave Italian unisono and French unisson.[6] Spanish also had a shortened form unisón, used by Quevedo.[4]
Earliest recorded meaning
In Santillana's Triumphete de Amor the word describes the songs of birds: unísonos, muy suaves, / triples, contras e tenores “in unison, very sweet, trebles, altos and tenors”, a list of musical voices.[7][4]
Semantic evolution
Autoridades (1739) defined it as having the same sound as something else, quoting Palomino's Museo pictórico of 1708, which compares the proportions of a building to voices in unison.[8][4] The Academy kept that definition through the 19th century and in 1899 added “tone” to it.[9][10] The noun for a passage in which all the voices or instruments sound the same notes, and the phrase al unísono “unanimously, with one accord”, are given by the current dictionary.[2][11] Records from the Americas run from Lima in 1791, of instruments with three strings in unison for each key, to the figurative al unísono of hearts beating together in Uruguay in 1928.[12]
