Play Value

Three pendulums with spherical weights are suspended from a common axis high above the heads of the observers. The axis can be set in motion at any velocity by a rope according to the belfry principle. The correct rhythm for pulling the string and controlling the turning velocity of the axis making the spheres swing one after the other, can be found by careful trial and error. The length of the pendulum arms determines the amount of vibration and has been designed in a way that the result is a harmonic, integral relationship between the vibrations. In the same way that the tones of 3 different bells ringing together results in an accord the spheres also meet repeatedly for a short moment in a vibrational pattern. This moment is especially fascinating for the observer.
