A wooden box conceals a brass drum with pins that rotate and catch the teeth of a comb, causing them to resonate. Each tooth has its own length and vibration frequency, and the pins are arranged to play a melody.
Properties
- 15 brass teeth of varying lengths
- Drum with randomly distributed pins (1-3 per column)
- Continuous rotation of the drum around its axis
- Damped sinusoidal oscillation of the tooth after being struck by a pin
