I have really no formal training in music but was really keen on learning so I picked this one up based on recommendations from the other reviewers. Some parts were a little hard, like compound time and borrowed time but I kept ploughing through and it just got easier. As of course with any book, don't expect to get all of your information from one source. I have some other books that explain a little better the Major/Natural Minor, Harmonic and Melodic Minor scales with regards to the pattern of intervals that define each. I would recommend picking up a basic book on how to read sheet music. With this and Basic Materials in Music Theory you'll have some good introductory foundatation for further studying and other texts. Is this product review negative?
