Lincolnshire Posy is a musical composition by Percy Grainger for concert band commissioned in 1937 by the American Bandmasters Association.[1] Considered by John Bird, the author of Grainger's biography, to be his masterpiece, the 16-minute-long work has six movements, each adapted from folk songs that Grainger had collected on a 1905–1906 trip to Lincolnshire, England.[2][3] In a similar fashion to these folk songs, many of the movements are in strophic form. The work debuted with three movements on March 7, 1937 performed by the Milwaukee Symphonic Band, a group composed of members from bands including the Blatz Brewery and Pabst Blue Ribbon beer factory worker bands in Milwaukee, Wisconsin.[4]
