upbeat

Etymology

It is formed from English up- + beat, originally a noun in music, the beat of a bar at which the conductor's hand or baton is raised.^[2][3][4][5] The adjective is a conversion of the noun:^[2] Etymonline traces it to the phrase “on the upbeat”, "improving, getting better", recorded from 1934 and much used in “Billboard” headlines in the early 1940s.^[3]

Earliest recorded meaning

In music, the beat of a bar at which the hand is raised, an unaccented beat: 1869, in Ouseley's Treatise on Counterpoint.^[2][5][3]

Semantic evolution

From music the noun passed to prosody in 1883, for an anacrusis, the unstressed syllable or syllables before the first stress of a line, and also for a stressed syllable.^[2][4] In the 1930s on the upbeat meant "on the rise, improving",^[3] and the noun was used figuratively for an optimistic mood or a pleasant development from 1950.^[2] The adjective, "cheerful, optimistic", first appears in 1947, in a New York Herald Tribune headline about a jazz set, naming Dizzy Gillespie, Yardbird Parker and Thelonius Monk;^[2][6][5] Green notes that it was first jazz use and originally American.^[6] Etymonline remarks that the cheerful sense seems to come only from the happy sound of the word, since the musical upbeat is no more positive than any other beat.^[3] Dictionary.com dates the "optimistic" sense to the early 1950s.^[7]
