Dr. Mattie Moss-Clark (March 26, 1925 – September 22, 1994) was an American gospel choir director and the mother of The Clark Sisters, a world-renowned gospel vocal group. Clark is credited for creating the three-part harmony (separating vocal parts into soprano, alto and tenor), a technique which is prevalent among gospel choirs today.
She completely revolutionized the music departments. She gave definition to the role of State Minister of Music, traveled year-round to every state in the country conducting workshops, rehearsals and musicals to prepare choirs for service on the National Church level and organized the structure of the National Music Convention of the Church of God in Christ. Dr. Clark introduced the workshop and seminar concept to the convention, and, along with her staff, structured classes for the convention and created “A Star Is Born”, the program where new talent was introduced before thousands. Despite failing health, Dr. Clark continued to record music into the last year of her life before succumbing to complications from diabetes on September 25, 1994 in Southfield, Michigan at the age of 69.
