Duke Ellington (1899–1974), composer, bandleader and pianist, elevated jazz to an orchestral art. From Cotton Club fame to global tours, his orchestra defined sophistication and swing. With Billy Strayhorn he created tone poems and suites—Black, Brown and Beige, Far East Suite, the Sacred Concerts—and standards including “Mood Indigo,” “It Don’t Mean a Thing,” and “Take the ‘A’ Train.”
