Harp guitar

Guitar-based string instrument

The harp guitar is a guitar-based stringed instrument generally defined as a "guitar, in any of its accepted forms, with any number of additional unstopped strings that can accommodate individual 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 lying off the main fretboard, typically played as an open string.
