Pentatono is a kinetic light and sound sculpture, where harmony and periodicity are the fundamental elements. Motion, sound and light; all are obeying the laws of the harmonic oscillation.

Five acrylic balls hanging from optical fibers, form five pendulums that are moving in the space using the thrust of small propellers. When a pendulum passes from the equilibrium position (the middle of the motion path) it emits a light pulse and sound tone. Each pendulum is “tuned” in a different note of a natural pentatonic scale. The lengths and hence the periods of the pendulums are accurately adjusted to form visual traveling waves, standing waves and quasi chaos.
