Lucier had a speech impediment so this piece was a sort of personal challenge/experiment for him.

Also, check out Lucier's Music On A Long Thin Wire. He used a power amp to run an audio from a signal generator into a wire and the wire sits in the field of a very strong magnet and vibrates, and the sound is extracted from piezo contact mics at each end of the wire. Very interesting stuff.

It is a part of the inspiration for the instrument I build and play, the Electroduochord, that uses a rotary magnetic bow.
