The Boswell Sisters were an American close harmony singing trio of the jazz and swing eras, consisting of three sisters: Martha Boswell (June 9, 1905 – July 2, 1958), Connie Boswell (later spelled "Connee", December 3, 1907 – October 11, 1976), and Helvetia "Vet" Boswell (May 20, 1911 – November 12, 1988). Hailing from uptown New Orleans, the group blended intricate harmonies and song arrangements featuring effects such as scat, instrumental imitation, ‘Boswellese’ gibberish, tempo and meter changes, major/minor juxtaposition, key changes, and incorporation of sections from other songs. They attained national prominence in the United States in the 1930s during the twilight of the Jazz Age and the onset of the Great Depression.
