After you build the frame, coils and amplifier, its time to test your wind harp. If everything is working, you should hear a loud "twang" when you pluck the steel wire.
For the best harmony, you can adjust the tension on the eye bolts so all the wires are the same frequency. The two inner wires are the strongest performers, while the two outer "passive" wires add some sound through mechanical connection at the single eye bolt end.
You will find that the harp responses to the slightest wind. Higher winds create higher frequencies. To protect the coils from rain, I placed a plastic cup as a cover above the coils.
When it rains, the wind harp becomes a rain harp, making very nice tones as the drops hit the wire.
