It may be a couple of years old, but Lyn posted a link to this remarkable presentation on her Facebook page, and I thought I’d flag it up here too. Imogen Heap is a musical pioneer who creates sounds using electronic equipment she controls by moving her body. That is, rather than pressing notes on a conventional instrument, she can wave her hand or shake her leg to generate sound. It’s quite fascinating to watch, and utterly postmodern; but what I find especially interesting is how this technology can be used by people with disabilities to create music. While you would probably need fairly good motor control to get something resembling a good tune going on this device, by effectively rendering the space around you an instrument, it certainly helps open up the boundaries of what is possible.
