Duke Ellington was an American jazz composer, pianist, and bandleader who made significant contributions to the genre from the 1920s through the 1970s. Known for his sophisticated and inventive compositions, he blended elements of blues, gospel, and swing into a distinctive sound often referred to as "Ellingtonian." His band, the Duke Ellington Orchestra, featured renowned musicians such as saxophonist Johnny Hodges and trumpeter Cootie Williams. Among his influential works are "Mood Indigo," "Sophisticated Lady," and the groundbreaking long-form composition "Black, Brown, and Beige."
