Etymology : Tunesmith was originally an Americanism, dating from the Jazz Age (roughly from the 1918 Armistice to the stock-market crash of 1929). Fittingly enough, an early citation for tunesmith (1923) is attributed to the American bandleader Paul Whiteman (1890–1967), who debuted George Gershwin’s Rhapsody in Blue (1924).
