Kinetics

I need to be doing a bit of research into this area. It struck me the other day that I should be looking at sculpture more attentively with a view to considering the sonic qualities of structures that have moving parts.
I first got this idea from Barbara Hepworth's Oval Form, (above) and then looked at other English sculptors and then to Force Fields, a catalogue from a kinetic art exhibition at the Hayward Gallery a decade or so ago.
I need to look further into Max Eastley's work and it will probably be useful to reference Harry Partch too as I ponder the idea of sound, sculpture and place.
