Wheel Harp
While adjusting his Hurdy Gurdy one day, Jon Jones of Southeast Missouri
thought it would be nice to be able to select which string came into
contact with the wheel, and also have lots and lots of strings!The
wheelharp consists of two tubular sound chambers, with a large circular
bow set between them. The 60 strings and keys are arranged in a radial
fashion around the wheel.
