Garry and his wife Diane founded Woodstock Chimes in 1979 and it remains based in New York's Hudson Valley. GRAMMY® Award-winning musician Garry Kvistad created the first Woodstock Chime from an aluminum lawn chair he found in a landfill. As a professional musician and instrument designer, he was fascinated by the Scales of Olympos, 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 Olympos was the first Woodstock Chime and is still one of our bestselling wind chimes.
