Edward Kennedy "Duke" Ellington, "King of the Keys," was born on April 29, 1899, in Washington, D.C. "He was a smooth-talkin', slick-steppin', piano-playin' kid," writes master wordsmith Andrea Pinkney in the rhythmic, fluid, swinging prose of this excellent biography for early readers. It was ragtime music that first "set Duke's fingers to wiggling." He got back to work and taught himself to "press on the pearlies." Soon 19-year-old Duke was playing compositions "smoother than a hairdo sleeked with pomade" at parties, pool halls, country clubs, and cabarets. Skipping from D.C.
