Wind chimes are a popular piece of garden decor because they bring the sweet sound of gentle breezes to your ears. Wind chimes not only make a great accessory in your own yard or garden - they also make great housewarming gifts for friends, family, neighbors and garden enthusiasts. Wind chimes are available in a variety of materials including aluminum, pewter, bamboo, shell, rock, wood, brass and glass, with each material providing its own unique sound. The sound of your wind chime will be determined by the material it's made from as well as its craftsmanship. However, some wind chimes come equipped with adjustable or removable wind catchers that allow you to adjust sensitivity to the wind. A large number of online retailers are dedicated specifically to the production of wind chimes and many provide audio clips so that you can listen to the sound of their wind chimes as you shop.
