Description: The harp guitar or [harp-guitar] is a guitar-based stringed instrument defined as a guitar or any of its accepted forms, having any number of additional unstopped strings that can accommodate plucking. The word “harp” is used in reference to its harp-like unstopped open strings. A harp guitar must have at least one unfretted string that runs parallel to the fingerboard while remaining outside of the fingerboard.
This family consists of many varieties of instrument configurations. Most readily identified are American harp guitars with either hollow arms, double necks or harp-like frames for supporting extra bass strings and European bass guitars [or contra guitars]. Other harp guitars feature treble or mid-range floating strings, or various combinations of multiple floating string banks along with a standard guitar neck.
