The book is plastic tabbed bound, but since it is over 600 pages long it is somewhat difficult to get the pages placed flatly. It also does not feel like it would be that durable because both the plastic tabs may break, or the slots on the pages would easily be torn. The size of the notes is also smaller than most music books. But for the price paid, this book gives good value as there are over 850 classical themes and melodies in one place.
Some pianists may turn up their noses at the idea of a classsical fake book, but I'd point out that many of these pieces were originally written for orchestra, or--in the case of the older ones--for harpsichord, clavichord, organ, and so on. Some are taken from operas. Indeed, many of the classical works we use with our students are arrangements rather than ur-texts.
My students and I often laugh at the term "fake book"; especially for the keyboard players, these books would be more accurately named "creative books." The performer is called upon to provide his/her own harmony arrangements and rhythmic patterns. For talented musicians, "fake books" are a great opportunity for creative expression. That said, it must also be emphasized that students must have a strong foundation in piano basics, and that the teaching of ur-texts is vital for any student.
We love the "Classical Fake Book"---a hoot and a half! Highly recommended.
