This is not to say that I would not use a small wind chime inside a home, especially if the chime has little rock crystals in it, for example.
According to traditional feng shui schools, wind chimes are used to cure negative energies, be it annual feng shui negative energies or challenging permanent fixtures inside a home.
If you need a strong metal feng shui element in a specific bagua area, such as Northwest, for example, a feng shui consultant might recommend a metal wind chime with 6 strings/bells, 6 being the feng shui number for Northwest. The best choice would be considered a chime with hollow tubes, so as to allow the potential Sha Chi to be transmuted into Sheng Chi quality of energy.
There are three main guidelines for best feng shui placement of wind chimes: the material they are made from, the number of rods/bells and the symbols present in its design.
Material. Always be mindful of matching the material/feng shui element of the wind chime with the bagua area element where you want to place it. A metal wind chime can be placed in the West, Northwest and North, while a wood/bamboo chime can be placed in the East, Southeast, and South bagua areas. Sometimes you can even find wind chimes made with porcelain or clay bells, in which case you are dealing with the earth feng shui element and will place them in earth or wood feng shui element bagua areas (Center, Southwest, Northeast, East and Southeast).
As with any feng shui cure, be mindful not to weaken or damage the main element of a bagua area. For example, do not place a metal wind chime in the East (wood element) or a wood chime in the earth element area (Southwest).
- Symbols. Many feng shui wind chimes come with traditional symbols, such as a feng shui Chi Lin wind chime for protection or the Mystic Knot wind chime for abundant energy. A clay wind chime with two hearts will obviously be an excellent choice for the Southwest / Love & Marriage area of your home or garden, while a chime with a Buddha image will work well with the feng shui energies of Northeast / Spiritual Growth and Self-Cultivation bagua area.
- Numbers. When using a chime as a feng shui cure, attention is also paid to the numbers of the rods/bells. Numbers 6 and 8 are the most popular numbers of bells in a wind chime in order to increase the beneficial energy; while 5 is considered best when you want to suppress bad energy, most often from an annual feng shui star.
