This book is awesome, it has almost all the songs from the movie and then some. The only downfall is that every single one of the songs is written in a very high key. If you can't sing soprano, you shouldn't buy this book. For example, the song "Over the Rainbow" is written in E flat. The highest note is a high F. Some of the songs go up to high A flat. Even the songs that the males are supposed to sing are unbelievably high. In conclusion, if you are an alto, you probably won't be able to sing these songs without hurting your voice. If you can't sing soprano, don't buy this book!
