According to Marshal McLuhan, the nature of the medium used to transmit a message is of greater importance than the message’s meaning or content. Our world is not just how we perceive it, it is precisely this: how we perceive it. Beethoven’s acoustic world as a composer gradually clouded and slowly vanished behind ever thicker wafts of mist. But simultaneously a new world came into being. The previous world metamorphed, or concentrated and condensed itself into a new shape: a thin line of lead.
