In wireless the sounds and voices of reality claimed relationship with the poetic word and the musical note; sounds born of earth and those born of the spirit found each other; and so music entered the material world, the world enveloped itself in music, and reality, newly created by thought in all its intensity, presented itself much more directly, objectively, and concretely than on printed paper: what hitherto had only been thought or described now appeared materialized as a corporeal reality.
