'This is a stunning achievement, and when scholars have had time to absorb its contents the study of Greek music and musical theory will never be the same again ... Its innovative, complex and multi-faceted methodology may be beyond what most others can hope to emulate at this level of sophistication, but once they have seen it in action no one will have any excuse for neglecting its potential, and we shall all have to absorb from it what lessons we can. In short, I believe that Hagel's book will revolutionise the discipline.' Andrew Barker, Professor of Classics, University of Birmingham 'I have no hesitation in pronouncing it a work of the highest originality and importance which future investigators will acknowledge as a landmark in the field.' Martin West, Professor of Greek, University of Oxford
