The author recommends the reader have several years of college-level music training. He uses harmonic/melodic analysis as one would use in dissecting W.A. Mozart, et al, in theory class. This is an interesting and insightful approach that sometimes gets a bit too clever, given the subject matter. The author demonstrates genuine admiration for the Beatles as composers/poets/performers, but occasionally becomes condescending, perhaps a product of his academic background. On the other hand, he seems to be very precise regarding who played what on which track--that's interesting for a musician at any level. All in all, an engrossing work. The more knowledge of music theory the reader possesses, the more he/she will enjoy this book.
