The tuning of our Bells of Paradise is based on an ancient system known as just intonation. This means that the frequencies at which the different tubes vibrate are related to one another by simple whole-number ratios. Tones that are related in this way produce the purest, most beautiful musical intervals. The elegant look and evocative sound of this chime will deeply satisfy your longing for paradise. Made of aluminum tubes that are specially suspended, these chimes resonate longer than other windchimes, bathing you in enduring harmony every time the wind blows. Hang this chime in your home or yard and enjoy the sounds of paradise right where you are. This chime carries a lifetime tuning guarantee.WOODSTOCK CHIMES THE ORIGINAL MUSICALLY TUNED WIND CHIMES. In 1979, the first Woodstock Chime was created by GRAMMY Award-winning musician Garry Kvistad from an aluminum lawn chair he found in a landfill. As a professional musician and instrument designer, he was fascinated by the Scales of Olympus, a 7th century pentatonic scale that can't be played on a modern piano. Garry had the idea to cut and tune the lawn chair chime tubes to the exact frequency of the ancient scale. The resulting Chimes of Olympus was the first Woodstock Chimes Wind Chimes and is still one of our bestselling wind chimes. Garry and his wife Diane founded Woodstock Chimes in 1979 and it remains based in New York's Hudson Valley.
