Listen to the soothing sound "illusion" of this Healing Chime as the precisely tuned tubes work together to create rich harmony. The illusion seems to create more tones than the number of its tubes, such as the low bass notes created in your ear! The result is as amazing as it is unique, since Woodstock uses a beautiful ancient tuning not heard on any modern instrument. This is called the Natural Harmonic Overtone Series. it's magic to your ears and a comfort to your mind. This wind chime has an unusual shape, an interesting "wave" clapper and is the perfect gift for someone who likes something that's "a little different"!
