The Woodstock Chimes Encore Chimes of the Eclipse is designed and handcrafted for superior musical performance and is hand-tuned to a five-note scale found all over the world. It acts in concert with the wind to create random patterns of wonderful music and will work in perfect harmony with all other Encore Collection chimes right in your own backyard. This chime showcases a unique and beautiful sounding feature called "octave doubling." Each note appears again one octave higher than the main scale. This expands the range of the chime while adding harmonic content and beauty to the sound. Introduced to celebrate the total solar eclipse of August 21, 2017, this chime will conjure the magic of this rare event with its ethereal music. This chime carries a lifetime tuning guarantee.
