If the kitchen has a window, then, you may consider especially a six hollow rod wind chime. If you really can't find a 6 hollow rod wind chime; then as a last resort, get those with hollow (rods). Your alternative of putting a clock with metal chime and pendulum is an alternative provided the pendulum is made of real metal. Nowadays, many "fake" pendulum clocks have pendulums that are made of plastic but sprayed painted in metallic colour.
