All the themes, and even the ones you didnt even think about when watching the films are here. For example, I never really noticed the theme around Professor Umbridge, however when playing these scores I can really see how the composer wanted to portray her pretty little personality, with that hint of dabbling deviousness.
The music in Harry Potter is a beautiful score, and the CD makes playing the tracks even better!
Some of the notes are rather high, so I would suggest you get the book if you are learning the 3rd register notes, or have really got them under your lips. I wouldn't recommend this book to anyone new to playing the flute - at around grade 3-4 standard simply due to the higher notes and odd timings/key signatures.
I really enjoy playing this tunes, and to be honest, I only really bought it to be able to play Double Trouble lol.
