Wind chimes are a type of percussion instrument constructed from suspended tubes, rods, or bells. There is a weight or surface for the objects to strike when the wind moves them.
Some people call wind chimes chance-based music since the sound comes from the random effects of wind blowing. Many wind-chimes are small, giving a fairly high-pitched tinkling sound. People often hang these from porch roofs or trees. The chimes pictured here are the largest I’ve seen so far. Their sound was deep and rich.
