The Rees Mariposa Concert Line Harp has the light weight and responsiveness prized by so many modern harpers. Luckily, the Mariposa does this without sacrificing any of the big voice and comprehensive dynamic range for which Rees harps are known. The Mariposa has a range of A to C and a string feel that is light but not so light it hides or distorts the voice. The Mariposa Harp comes with full Rees sharping levers and a narrow 3.5 inch (8.89 cm) shoulder that allows for complete freedom of movement. The Mariposa is 50 inches (127 cm) tall at the point and, depending upon the wood selected, weighs between 17 and 20 pounds (7.71 to 9.07 kg).

Like all Rees Concert Line Harps, the Mariposa includes a lifetime warranty.
