Dr. Mattie Moss Clark

Mattie Moss Clark was an American gospel choir director and the mother of The Clark Sisters, a gospel vocal group. She was the longest-serving international minister of music for the Church of God in Christ. "Her arrangements, perhaps influenced by her classical training, replaced the unison or two-part textures of earlier gospel music with three-part settings of the music for soprano, alto, and tenor voice ranges—a technique that remained common in gospel choir music for decades afterward."
