The Chinese chimes feature a familiar, major scale arrangement. The sounds of these chimes can be found throughout Chinese history. Many traditional Chinese instruments share this same tuning. This scale blends beautifully with the more complex Japanese and/or Balinese chimes. Music of the Spheres chimes are all handcrafted and are tuned to A440, which is a standard orchestral pitch. They are made of a tempered aluminum alloy tubing that will never rust. Each tube is coated with a sleek black corrosion-resistant finish that provides durability in all kinds of outdoor environments (acid rain, salt air, etc.).
