Named for the "blue planet," the planet we call home. The third planet from the sun, Earth is the only planet whose name does not come from Greek or Roman mythology. This wind chime is designed and handcrafted for superior musical performance. It is hand-tuned to a universal, pentatonic (five-note) scale and acts in concert with the wind to create random patterns of wonderful sound. Harmonizes beautifully with all the other Encore Collection windchimes. This chime carries a lifetime tuning guarantee.
