The Volta is taken from a Federico Fellini book about his films, what he characterizes as a changing of scene, or a turnaround; a new scene to him is called Volta. Y'know, changing of time and the changeover.

As the way we write songs and words, if it looks great on paper then to us it's like painting, so if it looks good meaning the second then people usually have a better interpretation than we ever would.
