Forms
impromptu (feminine impromptue, masculine plural impromptus, feminine plural impromptues)[1]
Etymology
It is borrowed from Latin in prōmptū (“in view, at hand”), an adverbial phrase of in (“in”) and prōmptū, the ablative of prōmptus (“a being at someone's disposal”), a noun formed on the supine of prōmō (“to take out, bring forth”).[2][3][4][5][6] The verb comes from an older compound of prō- and emō, which first meant “to take” and in Classical Latin “to buy”.[3] From “in view, before everyone”, the phrase came to mean in French “on the spot, without preparation”.[4][7] The musical sense was probably taken from German Impromptu, itself from French, which has it from 1827.[3]
Earliest recorded meaning
It is first recorded in 1651, in Loret's La Muse historique, as a noun for a piece improvised on the spot.[2][3][4]
Semantic evolution
The noun first named a short occasional poem, in principle unprepared, and a short play written for a particular occasion or on a topical subject, as Molière's L'Impromptu de Versailles (1663); this is now a term of literary history.[3][8] The general sense, anything done without preparation (1669), has gone out of use.[3][2] The adjective, “improvised”, is found in Molière in 1673, and is used of a meal made from whatever is at hand from 1718.[2][5] The adverbial phrase à l'impromptu (before 1755, Saint-Simon) has disappeared, and the plain adverb (1768, Rousseau) is literary and rare.[3][2]
In music the noun names a short instrumental piece of free form, usually for the piano, from Chopin (before 1849).[3][2] In 20th-century group psychology it has also been used for a happening.[3]
