The delicate yet brilliant sound created by this aluminum hand-crafted symphonic quality chime makes it the Stradivarius of Windchimes. The Mongolian scale is reminiscent of church and temple bells. The major pentatonic scale in root position is in the key of A. Genghis Khan conquered an empire unmatched in size, yet never heard chimes as lovely as these. Available in 5 sizes, the chimes are designed so that their pitch ranges overlap and complement each other. The larger chimes have a lower pitch and smaller chimes have a higher pitch. The same musical scale, or tuning, in different pitch ranges harmonize wonderfully, creating a magical "singing in parts" effect. You can never go wrong adding to your collection with another voice in the same scale to orchestrate your own unique "chime ensemble". Listen for a tuning that will make your mind relax and bring to you a sense of calm.
