acoustic aeolian aluminum downspout harp

This is a popular design on the internet and also the beginnings of making a acoustic audio art installation at my home. The audio linked below is not of very good quality. It has a lot of environmental noise and the harp itself is a bit “screechy” when the wind finally catches it good. I have a lot of experimenting to do to optimize this design because unlike the electric harp where you can just “turn it up” this relies on making a nicely resonant system. The length is about 4 feet and the string length is about 3.5 feet and the nylon fishing line is 50 pound – the heaviest I could find. I actually stuffed the zoom H2 -inside- the harp to get the recording. As with any aeolian harp the harmonic series, not the fundamental of the string, plays the central role in the pitch you hear.
