The 45 in. large wind chimes feature six aluminum powder-coated tubes, with the longest tube measuring 22.2 in. in length and 1.2 in. in diameter. Crafted entirely from aluminum, including the hook, top part, and pendulum, each component has a durable anodized bronze finish. Professional tuning experts hand-tune each tube to the pentatonic scale, resulting in a rich, resonant sound. High-density nylon cording and a heavy-duty striker enhance clear, soothing melodies that play softly in the wind, similar to calming church bells' tones. Thick tubing walls create a longer-lasting deep tone, while the reflective surface shines beautifully in sunlight, making them a lovely addition to any sunlit area. With adjustable bell length, they produce different scale sounds, suitable for various occasions like housewarming, wedding, or as a thoughtful gift.
