D. Good, an American jazz arranger active from the late 1940s through the 1970s, was a significant, albeit understated, force in big band jazz. Known for his sophisticated harmonic voicings and intricate counterpoint, Good’s arrangements blended traditional swing sensibilities with emerging bebop innovations. He notably contributed charts to orchestras led by figures such as Stan Kenton and Woody Herman, and his work with smaller ensembles showcased his versatility. Good’s arrangements are characterized by their clarity, rhythmic drive, and ability to elevate soloists, leaving an indelible mark on the evolution of jazz ensemble writing.
