Dubbed The First Lady of Song and Queen of Jazz, Ella Fitzgerald was the most popular female jazz singer in the United States for more than half a century. In her lifetime, she won 13 Grammy awards and sold over 40 million albums. Her voice was flexible, wide-ranging, accurate and ageless. She could sing sultry ballads, sweet jazz and imitate every instrument in an orchestra. Through Ella Fitzgerald's hits, the film reminds us the journey of this child from Harlem who became one of the world-famous singer that has played with the greatest: Louis Armstrong, Duke Ellington, Oscar Peterson, Charlie Parker, Frank Sinatra, Tom Jones, and many others. Ella was noted for her purity of tone, impeccable diction, phrasing and intonation, and a "horn-like" improvisational ability, what is called "scat", subsequently taken up by many jazz singers.
