The Woodstock Heroic Windbell - Antique Copper - Medium has a rich, tonal sound that instantly creates serenity. This medium sized bell chime is crafted of a single steel tube with a handsome antique copper powder coated finish. The interior clapper and aerodynamic wind sail create the sound. Designed to create harmony. Woodstock Percussion Wind Chimes are tuned using a computerized tuning process in order to achieve incomparably beautiful sound. These wind chimes also use an ancient tuning system known as just intonation. Because these notes fall between the notes of a piano (which is tuned using the modern equal temperament system), the chime has a unique, authentic quality. The frequencies at which the different tubes vibrate are integrally related, thus producing the purest musical intervals. Once you hear the beautiful tones created by these magical chimes, you will understand why they are so popular around the world. Every part of a Woodstock Chime is weather protected. Over time, however, those layers of protection can begin to wear. To enjoy your Woodstock Chimes for years to come, we suggest the following simple maintenance tips. Periodically, apply a thin layer of Danish or lemon oil with a clean cloth to the hardwood parts. Regular oiling will help protect the wood and retard the natural aging process. The tubes of traditional Woodstock Chimes are made of anodized aluminum that will not rust when exposed to the elements. However, over time, the aluminum may show pitting as a result of environmental factors. Please note this will not affect the beautiful tones of your chimes. Use mild soap and water (or a foaming, non-abrasive cleanser) to clean the tubes, glass or plastic parts. Try not to dampen the string.
