Duke Ellington (1899-1974) stands as one of the most consequential composers in American music. His output spanned over five decades and encompassed symphonic works, ballets, film scores, and thousands of songs for small ensembles and orchestras. Ellington's harmonic sophistication and orchestral imagination fundamentally expanded what jazz composition could be, influencing musicians far beyond the jazz world.
As a pianist and bandleader, Ellington understood instrumental voices with remarkable depth. His compositions for piano showcase his command of stride technique, chromatic harmony, and melodic storytelling. "I Got It Bad and That Ain't Good" exemplifies his gift for writing standards that endure through generations of musicians.
