Music is not simply something we hear. We experience it and love it; it is a primal human need. If, as the pianist Alfred Brendel put it, that we are able to "take music at its word," we confront questions that also moved the author since his adolescent years: What takes hold of me when I experience music? What reality touches me when music is playing? What happens physiologically in the human body when we experience and make music? The author approaches these questions from three perspectives: first, from his personal experience and active love of music; second, from the physiological perspective; and third, from Rudolf Steiner's spiritual science. – Dr. Husemann—author of The Harmony of the Human Body—shows how hearing is a sensory activity that encompasses far more than processes in the ear and brain, and that the whole body is involved. He also discusses the relationship between music and chemistry. Music is "chemistry from the inside." And finally, from 1915 to 1918, Rudolf Steiner developed a physiology of artistic imagination based on the movement of the cerebrospinal fluid during respiration. – Human Hearing and the Reality of Music is the first attempt to relate Steiner’s spiritual research to the findings of natural scientific research in this area.
