Abraham Dumisani Maraire (27 December 1944 – 25 November 1999), known to friends as "Dumi", was a master performer of the mbira, a traditional instrument of the Shona ethnic group of Zimbabwe. He specialized in the form of mbira called nyunga nyunga, as well as the Zimbabwean marimba. He introduced Zimbabwean music to North America, initiating a flourishing of Zimbabwean music in the Pacific Northwest that continues into the 21st century. Dumi is credited for his famous 1–15 number notation used on the nyunga nyunga mbira and for notating the song "Chemutengure" on the nyunga nyunga mbira. The song "Chemutengure" is used to teach mbira learners the technique of playing the instrument.
