Musical Chairs

I've been looking for a desk chair for a few months and this one caught my eye.   London based artist, Jo-Yun Wang, designed this swivel chair with musical caster wheels.  If you had a whole bunch of them in a room, it would produce quite a charming arrangement.  Although,  I would imagine that with every move and note produced over time,  the rate of delight would decrease and rate of annoyance would  creep up.  I wonder if it's possible to turn them off?
