Hugh Tracey Box F-15 Karimba
Get this if you want to play traditional African music in the nyunga nyunga F key - or if you have very large hands.
A new model of the Hugh Tracey African Tuned Karimba, in F, with 15 notes (ie, with the mbira nyunga nyunga note layout as opposed to the 17 note karimba layout), mounted on an alto box for a louder sound and more expression. The notes on this one are thought to represent the original mbira created some 1300 years ago in southern Africa.
Listen to these sound clips:
This matches the tuning, layout, and key of the mbira nyunga nyunga precisely.
