instrumentation

Etymology

The OED, in its 2017 revision, takes it as formed from English instrument + -ation, from the noun and, in later use, also from the verb,^[2][3] and compares the musical term Italian strumentazione (“orchestration”), recorded from 1813.^[2] Etymonline, Klein, the Shorter Oxford and Merriam-Webster take the word, or its musical sense, as borrowed from French instrumentation,^[4][5][6][7] which the OED records in French from 1823.^[2] The base noun comes from Old French instrument and Latin instrūmentum (“tool, apparatus”),^[4][8][5] from instruō (“to arrange, furnish”).^[8][5]

Earliest recorded meaning

The art of arranging music for a group of instruments, and the playing of instrumental music: both 1818, in the Quarterly Musical Magazine and Review.^[2] Etymonline dates the word to 1836, and Dictionary.com to 1835–45.^[4][3]

Semantic evolution

The word began in music and spread to other uses of instruments.^[2][5] The use of a tool in a medical or surgical procedure is recorded from 1832,^[2] and the general sense of doing something by means of an instrument or agent from 1841.^[2] The instruments of a band or a piece of music, taken together, are so called from 1884.^[2] Merriam-Webster's first date, 1845, is for the application of instruments for observation, measurement or control;^[7] the OED records the instruments installed in a machine or laboratory from 1872, and the design and installation of such instruments, originally in the United States, from 1932.^[2]
