My windharp can be heard on internet radio 24/7 at: windharp.webhop.net I play live recordings of the harp on my station and update every few days. The recordings get better as I improve the recording technique. When planes and helicopters fly overhead, the strings resonate and make some interesting effects. Other effects can be caused by insects landing on the strings or birds pecking at them. The strings will also react to loud nearby noises, tree branches swaying against the structure, cats jumping on the roof, trains blowing the horn. The electronics used to amplify the tiny signals from the pickups, are solar powered and have rechargeable batteries for backup power at night.
