Let the sound vibrations of this chime help keep your chakras in tune. Each of the 7 Zenergy Chakra Chime rods is tuned to the frequency of a chakra. By tapping a single rod with the mallet provided, and focusing all of your thoughts on that single tone, you can help maintain good energy flow within your body. The chakra stones can be placed next to the corresponding rod or held as it is played. Ancient Hindu beliefs say the secret to our happiness and well-being lies within. There are 7 major energy centers in our body -the 7 chakras- and each one vibrates at its own frequency. When they are all vibrating correctly, all the energy in our body is in balance and we enjoy good physical, mental and spiritual health. From left to right, the rods and stones of the Zenergy Chakra Chime represent: Muladhara/Base, G -16c/3107 H, Hematite; Svadhisthana/Sacral, Ab +32c/3367 Hz, Tiger's Eye; Manipura/Solar Plexus, B +38c/2020 Hz, Yellow Jade; Anahata/Heart, C# -31c/2178 Hz, Rose Quartz; Vishuddha/Throat, C# +33c/2260 Hz, Turquoise; Ajna/Brow, A +10c/3540 Hz, Lapis; Sahasrara/Crown, F -26c/2753 Hz, Amethyst. Chime is 11.5 x 5.25-inch; made of walnut finish ash wood with 7 silver polished aluminum rods, genuine stones, silkscreened base, and a mallet. 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 had the idea to cut and tune the lawn chair 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 windchimes. Garry and his wife Diane founded Woodstock Percussion, Inc. in 1979 and it remains a family-owned business in New York's Hudson Valley.
