About Alexander's Ragtime Band

Alexander's Ragtime Band is a 1938 American musical film released by 20th Century Fox that takes its name from the 1911 Irving Berlin song "Alexander's Ragtime Band" to tell a story of a society boy who scandalizes his family by pursuing a career in ragtime instead of "serious" music. The film generally traces the history of jazz music from the popularization of Ragtime in the early years of the 20th century to the acceptance of swing as an art form in the late 1930s using music composed by Berlin. The story spans more than two decades from the 1911 release of its name-sake song to some point in time after the 1933 release of "Heat Wave", presumably 1938.
