Intervals, Scales, Tones: And the Concert Pitch c = 128 Hz

"Why is that certain intervals, scales and tones sound genuine and others false? Is the modern person able to experience a qualitative difference in a tone's pitch? If so, what are the implications for modern concert pitch and how instruments of fixed tuning are tuned? Maria Renold tackles these and many other questions, providing a wealth of scientific data. Her pioneering work is the result of a lifetime's research into Western music's Classical Greek origins, as well as a search for new developments in modern times. She strives to deepen musical understanding through Rudolf Steiner's spiritual-scientific research, and she also elucidates many of Steiner's often puzzling statements about music."
