The Orb of Attunement is an enigmatic instrument which you can only play through subtle, gently swaying movements. The exterior is an icosahedron with no obvious controls. Inside, a Bela board and a gyroscope measure its movement and create a kind of virtual pendulum. The pendulum is induced to swing by slowly tilting the orb back and forth. Its sound is felt as much as heard: when, after steady and patient coaxing, the instrument begins to play, swishing sounds and the tone of a singing bowl are audible mainly to the player themselves, while the orb perceptibly shakes.
