I feel like this is all going the opposite way of how I envision the beauty of its potential.
Instead of making musicians have to dance to make sounds, dancers should have interactive environments for creating listenable music on the fly!
Most dancers just dance to some music that is already playing. Adaptable music would demonstrate the tightness of their dancing rhythm and perhaps other factors of expression would also be put into the equation.
I picture a large stage with multiple kinects and a light up touch floor. And maybe some snazzy sensors on their bodies haha.
Along the same lines, I've imagined DDR doing the opposite also. Instead of dancing To music, dance to create music (though I have to say, DDR pads are not as neat as you think as musical input devices........)
But yeah. I'd love to see a competition of dance moves creating music. Kind of like MPC competitions
