According to Marshall McLuhan, the nature of the medium through which a message is transmitted is more important than the meaning or content of the message. Our world is not only how we perceive it, it is how we perceive it. Beethoven's acoustic world of a composer has continuously dimmed and slowly disappeared behind thicker and thicker acoustic fog. But in parallel, a new world has emerged. The previous world has transformed or concentrated and condensed into a new form: a thin line of graphite. -Klaus Lang, 2019
