Stevie Wonder is an excellent lyricist, composer and musician. He mixed Afro-American traditions with rhythm & blues and rock. So he created today's soul music with keyboards and syncopating funk rhythms. His songs, such as "You are the sunshine of my life" or "I just call to say I love you", have become world successes. "Sir Duke" is a musical homage to the legendary composer and jazz musician Duke Ellington. A jewel of soul music!
