Because music therapists often use Mozart when working with people overcoming the challenges of autism, this chime is tuned to the opening notes of Mozart’s Piano Concerto No. 21. The design on this chime’s wind catcher has special significance. The interlocking, multi-colored puzzle piece has become an international symbol for autism. Its significance is multi-faceted, representing the mystery and complexity of different abilities seen among people with autism and symbolizing the diversity of the individuals affected. The bright colors are said to represent hope. It is a vivid symbol of solidarity among those who promote and support autism awareness. One aspect of autism is hyper-sensitivity to sound. This chime is designed with a specially-sized clapper so its soothing tones play more gently in the wind. Woodstock Chimes for Autism is a Woodstock Charitable Chime. 100% of the wholesale after-tax profits from this chime are donated to autism treatment and research. Woodstock Chimes are the original, musically-tuned, high-quality wind chimes known worldwide for their superior sound. When listening to a Woodstock Chime, you hear a fine musical instrument played by the wind, perfectly hand-tuned using the ancient system of “just intonation” based on natural harmonics. This means the frequencies at which the different chime tubes vibrate are related to one another by simple whole-number ratios. Tones that are related in this way produce the most beautiful musical intervals. The sonic effect is exceptionally pure and soothing. More than 30 years ago, the first Woodstock Chime was created by founder and owner 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 Olympos, a 7th century pentatonic scale that can’t be played on a modern piano. Garry and his wife Diane founded Woodstock Percussion, Inc. in 1979 and it remains a family-owned business in New York’s Hudson Valley.
