The Metallic Piano Wind Chime is different from other chimes as it is “polyphonic”. In laymen's terms, this means the musical texture consists of two or more simultaneous lines of independent melodies. Two lines of 7 matching length tubes hang between two wooden clappers. If you were to run one clapper though the center of the chime, you would hear over laying notes, in harmony. However, the chime is dependent on the wind's direction so you will receive a blended harmony. Certainly, a great addition to your Feng Shui garden. The platform is cherry stained wood with matching wind catchers. Made with rust-resistant, anodized aluminum, wood, & nylon. Features Polyphonic tones. Easy hanging metal hook included. Makes a great gift for any season or reason! Perfect gift for the Feng Shui enthusiast! Features removable wind catcher for easy customization. Measures approximately: 4 8.5" x 8.5" x 25"
