Experiment in F sharp minor

I love this piece by Janet Cardiff and George Buress Miller. This is the kind of interactive work that really inspires me- It is gentle, unexplainable and connective. It is with companionship, populace, that the piece becomes harmonic and resonant, and without it, the table of speakers is inanimate and silent. I love the simplicity of it and the idea of simple but harmonic music that is influenced by the presence of witnesses. I would be happy to make something like this, but with a sculptural element, and perhaps moving parts.
