Zimbabwe's Dumisani Maraire originated mbira nyunga nyunga number notation. The upper row keys (from left) are keys 2, 4, 6, 8, 10, 12, and 14 while the bottom row keys are notated as 1, 3, 5, 7, 9, 11, 13, and 15. Maraire brought awareness of this instrument to the United States when he came to the University of Washington as a visiting artist from 1968 to 1972.
