The Sharpsichord is a massive, solar-powered pin-barrel harp. It is primarily classified as a string instrument (or chordophone) and an electroacoustic instrument, because its sound is generated by strings vibrating and acoustically amplified by large metal horns.

A massive, solar-powered, pin-barrel harp invented by English sound sculptor Henry Dagg. it operates much like a giant music box, it features a heavy rotating stainless-steel cylinder with 11,520 holes. Users insert pegs into the cylinder, which pluck the instrument's 46 strings as it turns.

 

(Personal Note: This instrument was used for Bjork's "Sacrifice", from the album Biophillia. I was editing the relationships for the album and noticed that the Sharpsichord didn't exist)
