The author is a professor of the theory of music at Yale. As such, he's on to something here, but in his hands American popular music becomes little more than an academic subject. Missing in his heavyhanded academese is the accessability that has made these songs so popular in the first place. As a pianist who plays these songs over and over and who takes them seriously as a pre-eminent American contribution to world culture, I learned little except some biographical facts (inexplicably, though he has a gender-oriented chapter on women in this genre, he leaves out Dorothy Fields, one of the best in either sex). Additionally, the book is not inexpensive and no discount is offered. My thanks to Amazon for its liberal return policy. Note: There's an enthusiastic five-star review of this book which I suspect was written by the author or a close friend. It's undeserved. Alex Wilder's American Popular Music is much the better book, and much cheaper, too!
