What is "moraharpa"

The moraharpa is a modern name for an early predecessor of the nyckelharpa keyed fiddle; the primary example instrument dated 1526, was found in Mora, Sweden. A number of modern reproductions of the original moraharpa have been made since the 1980s, and the name moraharpa, in addition to referring to a single, specific instrument, has come to mean a type of nyckelharpa similar in design to the original moraharpa.
