Sound between Matter and Spirit

Frits Julius (author) 

For Goethe, there is only one source of knowledge: 'the world of experience, in which the world of ideas is included.' Starting with these words of Rudolf Steiner's on Goethe, Julius takes us on an exciting journey through the physics of sound production to the 'real power of the Word.'
