This book has it all: cognitive musicology, old-fashioned musicology, Schenkerian analysis, you name it. 600 large format pages of valuable information! I have used that extensively for my own proccupations – and I definitely plan to read the book again sometime. The only thing that I found intriguing is the author's disproportionate obsession with proportional tempi. Perhaps that comes from Epstein's extensive experience as an orchestra conductor.
