The Aeolian Harp (also called Wind Harp) is a string instrument that is played by natural wind. It sounds like layered feedback or drones with rich harmonic textures that will change continuously according to the wind direction, strength and consistency. One day, I bought the materials at the local DIY store and built a small Aeolian Harp. I brought the harp outside on windy days, but it made no sound at all. Through trial and error, by altering the string materials, tension, and the angle against the wind, it finally produced a sound.
The harp resonates with the surrounding environment, changing from place to place. I put two lavalier microphones into each of its two holes to clearly record the tiny resonant sounds, without too much wind interference. What is intriguing to me is that the recording will inevitably include environmental sounds from near and far which are condensed and slightly modulated by the harp. In a way, I use the harp as a kind of transducer as well as sounding body to interact with the environment through the forces of the wind. The recordings themselves are ecological, meteorological and geomorphological observations at a certain time and place.
