The Earth Harp is the longest stringed instrument in the world, with strings that extend up to 1,000 feet in length. The Earth Harp’s first installation featured the resonating chamber mounted on one side of a valley with the strings stretched out nearly 1,000 ft to the other side. How does the Earth Harp work? The Earth Harp is played using violin resin on cotton gloves and musical bows. The performer’s hands are run along the strings to created beautiful cello like tones. The act of rubbing the strings creates a longitudinal compression wave.
