EPIGRAPH “I think that the search for a universal answer to the questions raised by musical experi- ence will never be completely fulfilled; but we know that a question raised is often more significant than the answer received. Only a reckless spirit, today, would try to give a total explanation of music, but anyone who would never pose the problem is even more reckless.” Remembering the future LUCIANO BERIO v TABLE OF CONTENTS Signature Page............................................ iii Dedication.............................................. iv Epigraph...............................................v Table of Contents.......................................... vi List of Figures............................................ xi List of Tables............................................ xiii Acknowledgements........................................ xiv Vita................................................... xvii Abstract................................................ xviii Chapter 1.
