Hugh Tracey BOX Karimba
The Hugh Tracey African Tuned Karimba in A - but mounted on a treble 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.
You can learn more about the basic instrument at the "How to Play Karimba" Page. There are several books and instructional downloads available for this one.
Also available in several tunings: traditional African A; western A major; western A minor; G major (so it can be played with an Alto or Treble in G); or G minor.
