That is fascinating-- I had never heard of these.

Peter, there's a sound clip link near the topmost phto. The info on plans (and tuning) is about halfway down the very long page Jeri linked. Also around there, there is also a link to a 2-minute clip that explains the harp while one is playing in the background.

Now I understand how the Wichita Lineman might have heard his love singing through the wires... the author of this web page talks about listening to the Aeolian harp effect of the wind blowing through phone lines and power lines.
