“When, in the concert hall, I open my eyes, visible space seems to me cramped compared to that other space through which, a moment ago, the music was being unfolded, and even if I keep my eyes open while the piece is being played, I have the impression that the music is not really contained within this circumscribed and unimpressive space. It brings a new dimension stealing through the visible space, and in this it surges forward, just as, in victims of hallucinations, the clear space of things perceived is mysteriously duplicated by a ‘dark space’ in which other presences are possible.”
