Duke Ellington (1899-1974) stands as one of the most prolific and influential composers in American music history. His output spanned six decades and encompassed jazz standards, extended concert works, film scores, and sacred music, each bearing his unmistakable harmonic sophistication and orchestral sensibility.
Ellington's approach to composition went beyond typical jazz practice; he treated the ensemble itself as an instrument, writing idiomatically for individual musicians and exploring dissonance and chromaticism years ahead of his contemporaries. His music remains central to jazz education because it demonstrates how advanced harmonic thinking, blues tradition, and popular appeal can coexist.
