The Longboardharp is a new type of musical instrument. It features strings, a wooden resonance body and a wooden frame.



Most acoustic string instruments combine stratic and acoustic functions in one physical body.


The design of the Longboardharp separates the two functions. The strings (piano wire of different diameters) are held by the solid wooden frame, while the resonance body is standing on the strings.


The resonance body is situated in the precise middle of the strings. Hereby the string segments at both sides of the bridge sound in exactly the same tones. When the strings are excited at one side, the strings on the other side resonate.


The strings are played with bows, mallets and by plucking. Markings on the string indicate points with natural harmonics.


The current version of the Longboarharp has 6 strings which can be tuned in pentatonic scales based on G.

The Longboardharp is a semi-acoustic instrument. It can be played completely acoustic and with the help of amplification via two electromagnetic pickups (type Humbucker), which can be attached at each side of the instrument.


The acoustic and the amplified sounds have different properties. While the wooden resonance-chamber amplifies string vibrations and tactile sounds (picking strumming, bowing), the pickups register solely the string vibrations.


The pickups can be used for amplification and recording. The 1/4 inch (6.3mm) jacks allow for connecting regular sound equipment.


The recordings in the video above were made with a 4-channel recorder. (2 pickups and stereo microphone). In postproduction, a stereo mix was created. The Longboardharp was tuned in  G A C D F G‘


The longboardharp can also be played by two musicians simultaneously with one musician standing on each side of the instrument. Both musicians basically have the same musical possibilities, and can influence eachother‘s and the mutual sound.


The Longboardharp was created in 2016 and first publicly presented in 2019.
