The unique feature in this instrument is the string-tuning system. Each string is actually a pair of nylon strings twisted together. To tune them you either tighten by increasing the amount of twist, or slacken by untwisting (there’s a bit of hardware at the top of each string that you can grasp for twisting and untwisting). The shape is harp-like, but by some definitions this instrument doesn’t qualify as a harp because it doesn’t have a soundboard. To get more volume out of it, sometimes I stick a piezo pickup on it, and other times I screw a styrofoam ice chest to the front to provide a large sound-radiating surface.
In the sound clip the Twist Harp is joined by electric bass, soprano cooler guitar, and tines & echoes.
