With a reasonably good start, the book wavers in obscure directions; it tends to get judgmental about music appreciation, when it discusses works of different composers. The aesthetics of music is completely personal. The author should have focussed completely on the technical aspects of Western classical music. Definitely Not the book a beginner should read.
