There have to be a zillion opportunities to apply this idea to Melbourne. This movie by Whitevinyl, titled Solarbeat, shows the motion of the planets around the sun – a note is played each time a planet completes a year i.e. one orbit.
It could be applied to the motion of cars, trams, pedestrians, garbage trucks, ideas, footy, tourists, – in short anything that moves physically, metaphorically, etc. This really could be the sound of Melbourne.
