Begins with a review of the concepts presented in Level 2, then introduces new pieces and lessons in new keys to prepare the student for more advanced studies. Includes a "Just for Fun" section and an "Ambitious" section for the student who will devote a little extra effort toward learning some of the great masterworks that require additional practice.
In terms of the awesomeness of the songs included, this probably deserves 2 or 3 stars--they're usually pretty hokey, and the best you're going to get here is an arrangement of Scarborough Fair. But I think it does a very nice job teaching music theory and introducing new piano skills.
